UPS 467 Analysis of Residual Solvents in Pharmaceuticals

A headspace sampler maintains the sample at a constant temperature and then injects a fixed quantity of the gas phase generated into a GC unit. It is used for qualitative and quantitative analysis of volatile components in solid or liquid samples. The further strides in performance and user-friendly design of the HS-20 NX series provide strong support for a wide variety of analyses, from work in research departments to quality control.

Analysis of Residual Pesticide in Foods

When analyzing residual pesticides in foods, it is advantageous to use a high-sensitivity selective detector. In contrast, an FID, which is suitable for a general-purpose application, is used to comprehensively measure many different pesticides.
Using an ECD/FPD detector configuration provides high-sensitivity analysis of phosphorus, sulfur, and halogen while an FID measures a wide variety of pesticides.

Analysis of Impurities in Hydrogen Gas

Dual BIDs

The Nexis GC-2030 can be equipped with two BIDs. More qualitative information can be obtained from the same sample by attaching columns with different separation characteristics.

O2: approx. 100 ppm, N2: approx. 340 ppm,
Other impurities: approx. 0.2 ppm
O2: approx. 25 ppm, N2: approx. 160 ppm, CO2: approx. 0.4 ppm,
Other impurities: approx. 0.2 ppm

Refinery Gas Analysis System

Specialized systems can be configured by installing multiple valves and columns in the standard Nexis GC-2030 installation space. Inorganic gases, hydrocarbons, hydrogen sulfides, and other components can be analyzed within five and a half minutes. Method development is not required because systems are assembled and tested in advance at the factory, prior to arriving at your lab.

Analysis of VOCs in Work Environments
Trace components in the air can be concentrated for measurement via thermal desorption. The TD-30 can accommodate up to 120 samples, and thanks to the repeated collection function, if a precious sample is analyzed incorrectly, it can be measured again.
