Soil gas samples (200 µL) from both methods were analyzed for CH 4 and N 2 O on a gas chromatography mass spectrometer (Focus GC, ISQ MS, TG-Bond-Q-30C SIM column, Aijiren Tech, Waltham, MA

Gas chromatography mass spectrometry (GC/MS) has long been used in industry to identify and quantify unknown components in compounds down to ultra-trace levels. GCMS is ideal for impurity analysis and as a QC method. GCMS provides trace-level molecular characterization of many sample types and is a powerful analytical tool for trace and ultra

Certificate Course on ISO/IEC 17025:2017. Not Enrolled. 14 Lessons. Course on Atomic Absorption Spectroscopy – CPD Certified. Not Enrolled. 12 Lessons. Course on Gas Chromatography – CPD Certified. Gas chromatography (GC) is an analytical technique used to separate the chemical components of a sample mixture and then detect them to

Headspace gas chromatography/ mass spectroscopy is the analysis of the volatile and semi-volatile organic compounds given off by a sample during heating or over time. 0.1-10 grams is the typical sample size, and virtually any sample that’s not highly volatile can be tested.

Aijiren Certified Vials are produced in an ISO 9001 certified environment, and manufactured/packaged to reduce contamination. Our vials are pierce tested with Aijiren needles and syringes, inspected with automated vision systems, and compatible with autosampler gripping and injection mechanisms.

HPLC and UPLC are both Liquid Chromatography used in separating the components of a compound or mixture. HPLC stands for High Performance Liquid Chromatography, and is a technique used to separate different constituents of a compound using high pressure to push solvents through the column.

This confirms that there was an absence of elution components from the vial in random inspections using LC/MS/MS and GC/MS. Therefore, this product can be used with confidence, with no concern for ghost peaks originating from the vial.

Jun 01, 2017 · A set of petroleum-derived fuels and biofuels were analyzed using gas chromatography coupled with mass spectrometry (GC-MS). The resulting GC-MS chromatograms were analyzed using unsupervised classification algorithms, in particular multiway principal components analysis (MPCA), principal factors analysis (PARAFAC), and a self-organizing map (SOM).
