![[Analysis Case] Investigation of Adhering Components Before and After Cleaning of Mechanical Parts](https://image.mono.ipros.com/public/product/image/779/2000832730/IPROS78688074459924107090.png?w=280&h=280)
It is possible to evaluate cleaning effectiveness and identify contaminants.
When overhauling mechanical parts such as pumps and engines, there are cases where parts are cleaned and reused. If the cleaning does not sufficiently remove dirt, there is a risk of malfunctions occurring in the assembled machinery. To investigate the presence of dirt or to analyze the components that are attached, thermal desorption gas chromatography/mass spectrometry (TD-GC/MS) is effective. By heating the sample at a high temperature (up to 350°C), the attached organic substances can be volatilized and measured using GC/MS. This method is useful for identifying the attached components, comparing the amount of attachment before and after cleaning, and assessing the degree of cleaning based on different cleaning methods. Measurement method: GC/MS Product field: Manufacturing equipment and parts Analysis purpose: Composition evaluation and identification For more details, please download the materials or contact us.

![[Case Study] Development of an mRNA Impurity Measurement Method Using Dual LC](https://image.mono.ipros.com/public/product/image/5d0/2001503005/IPROS3098837903499788185.png?w=280&h=280)
Efficiently examine separation conditions through method scouting; dual LC allows for the operation of ion exchange and ion-pair reversed-phase conditions within the same system.
The Thermo Scientific Vanquish Duo UHPLC system is a dual LC system equipped with two independent flow paths, allowing for parallel condition testing of different separation chemistries, such as the combination of ion exchange chromatography (IEX) and ion-pair reverse phase chromatography (IP-RP), within the same system. This technical document utilizes a method scouting kit to examine various ion-pairing agents, gradient conditions, pH, and column temperatures, achieving good peak shapes for mRNA and high-sensitivity detection of impurities. By simultaneously investigating IEX and IP-RP, it is possible to understand the separation characteristics of the sample, enabling efficient determination of separation conditions. With high separation capability and sensitivity, impurities can be effectively detected during post-transcription purification, allowing for reliable mRNA purification. **Features** - Simultaneous examination of two different separation chemistries (IEX and IP-RP) using the same device. - High-sensitivity detection of impurities in post-transcription purification through mRNA profiling. - Efficient determination of suitable separation conditions using the method scouting kit. - Examination of up to 10 solvents per column type to determine appropriate mobile phase conditions.
Diverse versatility from upstream to downstream.
The introduction of LC/MS in bioprocessing is progressing overseas. You might be thinking, "I use LC, but MS is difficult..." BioAccord is here to solve that concern. With its simple operability and high reproducibility, it is a recommended system for bioprocess engineers. Do you have any such impressions or questions? ■ Is evaluating aggregates sufficient with just LC? With LC/MS, you can also confirm the intact mass. ■ Is it enough to just confirm major post-translational modifications? With LC/MS, you can perform peptide mapping and post-translational modifications in a single analysis. ■ Is it sufficient to monitor only amino acids? With LC/MS, you can comprehensively detect components* in the culture medium, and integration with JMP is also possible. *Dependent on component concentration. ■ How do you preprocess samples taken from a bioreactor? It's easier than you think. After filtering out particulates, you can simply dilute with water or buffer to measure the intact mass of components and antibodies in the medium. Waters has a walk-up solution to automate this process. *For details, please download the catalog.

![[Analysis Case] Analysis of Smartphone Sealants by Pyrolysis GC/MS](https://image.mono.ipros.com/public/product/image/6a7/2000246610/IPROS3480187425868828986.jpg?w=280&h=280)
Analysis of UV-curable materials is possible through two-stage heating.
Using a two-stage heating method with thermal decomposition GC/MS, we analyzed the material of the sealing agent around the display of commercially available smartphones. By heating the sample at a low temperature (250°C) and measuring the gas components generated using GC/MS, we can detect residual monomers and low molecular weight additives (polymerization initiators, antioxidants). Subsequently, by heating at a high temperature (550°C), we can decompose the polymers and estimate their constituent components. This revealed that the sealing agent is made of a UV-curable material.
![[Analysis Case] Analysis of Evolved Gases during High-Temperature Heating in Air by Pyrolysis GC/MS](https://image.mono.ipros.com/public/product/image/655/2000246982/IPROS6886542884426710186.jpg?w=280&h=280)
It is possible to track the thermal decomposition behavior in the presence of oxygen.
The decomposition behavior of materials when heated in a vacuum or in inert gases such as nitrogen can differ from that when heated in air. Therefore, when conducting gas emission analysis, it is desirable to heat the materials in an environment that closely resembles the actual conditions to which they are exposed. In this case, a comparison of the gases emitted during the pyrolysis of polystyrene at 550°C in helium and in air was conducted. Only hydrocarbon compounds were detected in helium, whereas reaction products with oxygen, such as benzaldehyde, were also detected in air.

Conduct qualitative analysis of the "main components of odor" and "allergen identification" generated from the sample.
We would like to introduce a case study regarding a complaint from a product user about health issues caused by the product. This investigation focused on the odor components of the product using a Headspace Gas Chromatography Mass Spectrometry (HS-GC-MS) system. A portion of the product was sealed in a container and heated to release odor components. The released odor components in the container were measured, and the detected components were analyzed. It was found that the detected odor components were substances that can cause allergies (limonene and menthol). Our company proposes appropriate methods tailored to customer requests and the characteristics of samples, providing reliable data backed by extensive experience and technical expertise.

![[Case Study] Identification of Unknown Components Using Directly Introduced Probe High-Resolution GCMS](https://image.mono.ipros.com/public/product/image/b3f/2000745605/IPROS42394862835360127790.png?w=280&h=280)
Rapid identification of unknown components using high-resolution GCMS with a direct introduction probe without chromatography.
The detection and identification of compounds of unknown origin is challenging, often involving complex volcanic processes, and it takes time to obtain results. Additionally, high reliability is required for final identification, which necessitates the confirmation of multifaceted information. By measuring the molecular weight of chemical substances with sufficient accuracy, it is possible to determine the elemental composition and identify the chemical structure of the substance using isotope ratios and fragmentation patterns. Using high-resolution GCMS allows for the reliable detection of target components from complex matrices due to its high mass resolution and mass accuracy. This technical document introduces a method for reliably identifying unknown substances almost instantaneously. It connects a direct injection probe to our high-resolution GCMS (Orbitrap GC-MS system) and rapidly identifies compounds using both electron ionization and chemical ionization.
