Helium gas is facing issues of rising costs and unstable supply due to the increasing demand year by year while the means of production are limited. The Helium Saver Module is designed to reduce helium gas consumption by adjusting the flow rate of the split line when measurements are not being taken or during the measurement process. By installing our GC-specific Helium Saver Module, helium gas is directly supplied to the carrier gas entering the analytical column, while nitrogen gas is used for the split flow. This significantly reduces the consumption of helium gas that was previously used for the split flow, which accounted for the majority of carrier gas consumption. Furthermore, since there is no need to change the carrier gas, the hassle of re-evaluating analytical conditions is eliminated.

In recent years, the demand for non-target analysis has been increasing in many fields, such as odor analysis and impurity analysis, using GC-MS. This involves conducting comprehensive measurements without specifying the measurement targets through full scan MS and extracting valuable information from the vast spectral data obtained. Since the full scan MS data obtained from GC-MS can contain information on hundreds to thousands of compounds, efficiently identifying valuable information from this data is a very important challenge. Additionally, it is crucial to select the optimal pretreatment device considering high extraction capability, broad coverage, and the form and properties of the sample, in order to comprehensively extract samples without loss and introduce them into GC-MS. This application note presents a case study of non-target analysis that combines a system connecting a pretreatment device to a Thermo Scientific GC-MS instrument with AnalyzerPro, a deconvolution software from SpectralWorks.

The detection and quantification of pesticides, contaminants, and other chemical residues is particularly important when the food is intended for infants. Many pesticide products have a maximum residue limit (MRL) typically set at 10 μg/kg, but the European Union (EU) has established MRLs for certain pesticides banned for use in baby food at 3 to 8 μg/kg. In the worst-case scenario, such pesticides and their metabolites can exceed the acceptable daily intake (ADI) for infants. The high sensitivity and selectivity of GC-MS/MS allow for the detection and quantification of regulated residues even in baby food containing multiple ingredients. This application note presents a case study of the analysis of pesticide residues in baby food using a high-sensitivity Advanced EI ion source. The increased sensitivity allows for the dilution of sample extracts, reduces system contamination, and is expected to enhance laboratory productivity.

Odor analysis is an important analytical theme that is widely conducted not only in food but also in exhaust from equipment, the atmosphere, and the construction field.

The detection and identification of illegal substances or suspicious materials of unknown origin is difficult, often involving complex analytical processes, which can take time to yield final results. Furthermore, high reliability, confirmed by many points, is essential for final identification. Generally, all suspicious substances seized by law enforcement agencies must be sent to scientific investigation agencies for testing. Drug testing kits can be used for the identification of certain classes of drugs, but identifying the exact active substances in unknown powders or liquids, especially new substances in drugs like "legal highs," is often challenging. When using mass spectrometry, high mass accuracy data is essential to gain the necessary selectivity in complex matrices and enhance the reliability of compound identification. By measuring the molecular weight of chemical substances with sufficient accuracy, analysts can determine the elemental composition and identify the chemical structure of substances using isotope ratios and fragmentation patterns. This application note describes a method for reliably identifying unknown substances almost instantaneously. This method connects a direct insertion probe (DIP) to the mass spectrometer and rapidly identifies compounds using both electron ionization (EI) and chemical ionization (CI).

Packaging materials are essential for maintaining the integrity of food and for safe handling, transportation, and storage. Common food packaging materials include polymer-based films and paper-based coatings, which are often layered and printed on the outside with inks, dyes, or coatings for consumer appeal and convenience. The chemical components of such food packaging (particularly those derived from polymers, dyes, and inks) can migrate into food, altering its sensory properties and composition, and potentially posing health risks to consumers. Therefore, regulatory measures are implemented to prevent the migration of food contact material components that could affect human health, alter composition, or change the sensory properties of the product. This application note reports quantitative results of residual solvent analysis in food packaging materials.

Information has become increasingly diverse in recent years, and there is a growing demand for tools that can handle vast amounts of data accurately and conveniently. For example, analytical researchers may find it sufficient to obtain calibration curves and quantitative data from chromatograms and spectral information as chromatography data. However, it may be necessary to ensure that these data were obtained under conditions where the equipment operated correctly. Computerized systems used in the development and manufacturing of pharmaceuticals and medical devices must be properly developed, implemented, and operated, leaving evidence that proves there are no issues with the quality of the pharmaceuticals or medical devices, as well as their quality assurance. Computerized System Validation (CSV) is mandated by pharmaceutical regulations. Achieving Data Integrity (DI) requires essential support from software. This technical note outlines the overview of DI and the software functions required for DI, and introduces examples of residual solvent testing as specified in USP<467> using a headspace-specific autosampler and gas chromatograph that comply with DI.

Surgical masks are worn by healthcare professionals during tasks such as surgeries, and like other medical devices, they need to be sterilized to eliminate bacteria and viruses. In some countries, sterilization using ethylene oxide is performed. On the other hand, the Centers for Disease Control and Prevention (CDC) has stated that "ethylene oxide may have harmful effects on the wearer, and therefore is not recommended for the sterilization of masks that are worn on the face," and the Occupational Safety and Health Administration (OSHA) does not approve the use of ethylene oxide as a sterilant. Therefore, it is necessary to test that ethylene oxide and 2-chloroethanol, which is generated during its sterilization process, are sufficiently removed from the final product. This technical document introduces a high-sensitivity and cost-effective analysis method for ethylene oxide and 2-chloroethanol in medical masks using capillary column GC-FID analysis.

The processed foods we consume develop unique flavors and aromas due to various differences in the quantities and origins of the ingredients used, as well as cooking times, even if they share the same name. Understanding these differences at the component level is crucial in food research, and the use of GC/MS methods is expected to shed light on volatile components, which are believed to be factors influencing aroma. Non-target analysis that encompasses all contained components has been considered challenging due to the vast amount of information and the complexity of analytical operations. To obtain reliable results, efficient sampling methods, chromatographic separation, advanced mass separation, and software for smooth statistical analysis of the data are required. In this technical document, we present a workflow using high-resolution GC-MS (Orbitrap GC-MS) and Compound Discoverer software for low molecular analysis, as a solution to smoothly and accurately address this complex food comparison, exemplified by the inter-sample comparison of commercially available meat sauces from three food manufacturers.

Polycyclic aromatic hydrocarbons (PAHs) are components generated from the heating of organic materials, and due to concerns about their carcinogenicity and other health effects, PAHs present in food are regulated in some countries and regions. In particular, edible oils may undergo heating as a pretreatment during extraction from raw materials, which raises the possibility that PAHs could be generated during the thermal processing, even if the raw materials themselves do not contain PAHs. Since various countries have established standard values for PAHs, safety inspections may be required when exporting food abroad. These standard values are becoming stricter year by year, and high-sensitivity detection measurement devices are needed to accurately quantify these standard values. This application note presents a case of highly sensitive quantification of PAHs without interference from matrix components, achieved using the high mass resolution and mass accuracy of the Orbitrap GC-M system, a high-resolution GCMS. Data acquisition is performed through full scan measurements, making method development easier and enabling retrospective analysis (such as checking whether newly regulated components were present in previously measured samples).

In the quantitative analysis of pesticide residues in food, triple quadrupole mass spectrometers such as GC-MS/MS and LC-MS/MS are commonly used. This is because they can separate trace amounts of pesticides from the food matrix and detect peaks with high sensitivity.

Organic solvents are widely used in the synthesis of pharmaceuticals, but they cannot always be completely removed during the manufacturing process. To ensure safety, the final product is tested to evaluate whether the solvents used have been efficiently removed and, if any remain, whether their concentrations are within acceptable limits. The United States Pharmacopeia (USP) method <467> provides detailed procedures for screening, confirming, and quantifying residual solvents, including sample preparation and analytical conditions. The new TriPlus 500 HS autosampler adopts an innovative design with a flow path that directly connects the heated valve to the GC column. This means high-precision sample introduction and excellent reproducibility of peak areas. Furthermore, by continuously purging the sample path, the robustness and reliability of the system are ensured, reducing the risk of contamination and carryover (which is important when analyzing high-boiling residual solvents). This technical document reports the results of residual solvent analysis conducted in accordance with USP <467>, using the TriPlus 500 HS autosampler and FID as the optimal detector.

The chemical components of food packaging (especially those derived from polymers, dyes, and inks) can pose health risks to consumers by migrating into food. In the United States, the migration limit applicable to residual solvents and non-volatile food additives is 50 ppm. Additionally, the accurate quantification of residual solvents in flexible packaging is regulated by established methods such as EN 13628-1:2002. When analyzing volatile impurities in solid polymers using liquid injection, a cumbersome process of dissolving the sample in an appropriate solvent is required. Furthermore, high-viscosity solutions containing non-volatile long-chain polymers can contaminate the GC injector port, leading to increased analysis costs due to frequent maintenance. On the other hand, using headspace sampling allows for the rapid and easy extraction of volatile components from food packaging samples, eliminating the need for time-consuming sample preparation. This technical document presents the quantitative results of residual solvent analysis in food packaging materials conducted using the TriPlus 500 headspace (HS) autosampler. The dual detector configuration of FID/MS enabled the detection, identification (using hydrogen flame ionization detection), and confirmation (using mass spectrometry detection) of unknown impurities.
