Simultaneous analysis of odor components.

Simultaneous analysis of odor components.

Identification of odor components using gas chromatography-mass spectrometry.

Odors are commonly expressed in various ways, such as "fragrance" that gives pleasure and "stench" that causes discomfort. Odors rarely exist as a single type of odor component; instead, they are typically a mixture of various odor components. To visualize these complex odors, instrumental analysis using gas chromatography-mass spectrometry (GC/MS) is effective. This document introduces the flow of odor component analysis and presents a case study of simultaneous analysis of unpleasant odors.

[Analysis Case] Structural Analysis of End Groups of Polycarbonate

[Analysis Case] Structural Analysis of End Groups of Polycarbonate

End groups of polycarbonate can be distinguished by the manufacturing method using thermal decomposition GC/MS!

Our organization offers analysis of the end group structure of polycarbonate. Polycarbonate is an engineering plastic known for its excellent impact resistance and heat resistance, and it is widely used as a material in electrical, electronic, and optical devices. There are mainly two methods of manufacturing polycarbonate, and the end group structure, which affects the physical properties of the polymer, varies depending on the manufacturing method. Since the end group portion of the polymer is small compared to the main chain, the analytical methods available for its structural analysis are limited. Here, we present a case study evaluating the end group structure of polycarbonate using thermal decomposition GC/MS.

[Application Data] Examples of improvements for easily adsorbed basic compounds

[Application Data] Examples of improvements for easily adsorbed basic compounds

An example of improvement using post-column method for basic compounds that easily adsorb to the Sornak tube!

When using the Solnack tube CFAN under phosphate buffer conditions, if the compound being measured is basic, it may become dissociated and adsorb to the resin inside the tube. Therefore, by adding ammonia water using the post-column method before introducing the tube, we thought that making the eluent inside the tube basic and keeping the target compound in its non-dissociated form could suppress adsorption. We attempted to improve adsorption to the Solnack tube by adding ammonia water using the post-column method. For details on conditions and analysis results, please download the catalog. 【LC Conditions (Partial)】 ■ Equipment: Agilent 1200 ■ Detector: UV (215 nm) ■ Sample: 20 ppm solution of hydrochloride doxepin reagent ■ Injection volume: 5 μL ■ Post-column: 200 mM ammonia water at 0.05 ml/min *For more details, please refer to the PDF document or feel free to contact us.

Application Data: Example of LC/MS Measurement by Decyl Sulfate Removal

Application Data: Example of LC/MS Measurement by Decyl Sulfate Removal

Using the desalting tube "Solnac Tube" for LC/MS! Online removal of dodecyl sulfate.

When analyzing highly polar basic compounds using reversed-phase partition chromatography, adding acidic ionic species to the eluent can enhance retention by forming neutral ion pairs through ionic bonding. Sodium dodecyl sulfate, used as an ion-pairing reagent, is non-volatile and can precipitate in the ionization section of the MS, making it difficult to introduce, and it can suppress the ionization of the analytes, thus it cannot be used for online LC/MS measurements. In this case, we used a system with ammonium dodecyl sulfate (ADS) added, using caffeine and thiamine hydrochloride as samples, and removed dodecyl sulfate from the sample solution using a Solnack tube to perform positive ion measurements. For details on the conditions and analysis results, please download the catalog. 【Infusion Conditions】 ■Samples: (1) Caffeine 10 ppm solution, (2) Thiamine hydrochloride 10 ppm solution ■Solvent: CH3CN / H2O = 50 / 50 + 10 mM Ammonium dodecyl sulfate ■Flow rate: 0.1 ml/min *For more details, please refer to the PDF document or feel free to contact us.

[Analysis Case] Qualitative Analysis of Fluorinated Gases

[Analysis Case] Qualitative Analysis of Fluorinated Gases

Qualitative analysis of specific freons (CFC/HCFC) and alternative freons (HFC) is possible.

Freon gases are utilized in various applications such as refrigerants, foaming agents, semiconductors, and cleaning agents for precision parts due to their chemically stable nature and minimal impact on human health. On the other hand, they are substances that contribute to ozone layer depletion and global warming, which is why they are regulated by law. In this case, Freon gases were analyzed using GC/MS, and the separation analysis of CF4, which has low polarity and is difficult to separate among PFCs, was conducted. By using GC/MS, it is possible to qualitatively analyze specific Freons such as CFCs, HCFCs, and alternative Freons like HFCs and PFCs.

[Analysis Case] Oil Analysis (GC/MS Edition)

[Analysis Case] Oil Analysis (GC/MS Edition)

When oil contamination is suspected, it is possible to distinguish between types of oil and estimate the source!

Our organization is capable of identifying the composition of petroleum products, evaluating molecular weight distribution, and distinguishing types of oils. Petroleum products such as oils and greases are mixtures of hydrocarbons with various compositions, and GC/MS methods are effective for their qualitative analysis. Here, we present a case study where commercially available oils with different molecular weight distributions were measured using soft ionization methods. Compared to hard ionization methods (EI), soft ionization methods (FI and FD) allow for the detection of molecular ions, making them effective for evaluating the composition of oil components. In particular, the FD method can also be applied to evaluate oils containing high molecular weight components that are difficult to volatilize.

[Application Data] Example of Analysis of Cationic Surfactants

[Application Data] Example of Analysis of Cationic Surfactants

Application to ion pair reagents! Analysis example using the "Solnac Tube" for desalting in LC/MS.

Surfactants that change their properties at interfaces have both "hydrophilic" and "lipophilic" structural components within a single molecule. The hydrophilic part of surfactants often contains highly polar acids or bases, so in HPLC analysis, it is also possible to use a mobile phase with added ion-pair reagents such as sodium dodecyl sulfate (SDS). As a sample, a mixed solution of cationic surfactants such as tetrabutylammonium chloride and cetylpyridinium chloride was used for LC/MS measurements. For details on conditions and analysis results, please download the catalog. 【LC Conditions (Partial)】 ■ Equipment: Agilent 1200 ■ Flow rate: 0.3 ml/min ■ Detector: UV (215 nm) ■ Sample: Each 2.5 ppm solution ■ Injection volume: 5 μL *For more details, please refer to the PDF document or feel free to contact us.

Application Data: Example of Negative Ion Measurement by TFA Removal

Application Data: Example of Negative Ion Measurement by TFA Removal

Using the desalting tube "Solnac Tube" for LC/MS! Removing TFA and conducting negative ion measurement.

When analyzing acidic compounds using reversed-phase partition chromatography, an acidic mobile phase (set to a pH more than 2 units lower than the pKa of the analyte) may be used to suppress dissociation. Common acidic mobile phases suitable for use in LC/MS include acetic acid, formic acid, and trifluoroacetic acid (TFA), with TFA being appropriate for use at low pH. However, TFA is considered to have too high an acidity, which can lead to ionization suppression with almost 100% probability when detecting the analyte as a negative ion. TFA was removed from the eluent using a Solnac tube, and negative ion measurements were conducted. For details on conditions and analysis results, please download the catalog. 【LC Conditions (Partial)】 ■ Equipment: Agilent 1200 ■ Flow rate: 0.3 ml/min ■ Detector: UV (210 nm) ■ Sample: Tryptophan 20 ppm solution ■ Injection volume: 5 μL *For more details, please refer to the PDF document or feel free to contact us.
