Jan 10, 2022 · They’ve been through a standardisation process to fit most, if not all, HPLC and GC autosamplers (their common dimensions: 12x32mm). In terms of volumes, they range from 1.5 to 2mL. When working with limited sample volumes (<200µL), it is possible to select high recovery vials or add inserts to regular vials to increase sample height.

Jun 17, 2014 · Gas Chromatography. Mass Spectrometry will then be used to identify as many components in the gasoline as possible and to determine the concentration of ethanol and benzene in the sample. BACKGROUND GC-MS is a “hyphenated” experimental technique that incorporates two widely used methods in tandem.

toxicity, and is a common component found in toothpaste which is frequently combined with Glycerin. The work presented in this application note uses GC-MS to analyse DEG and EG in toothpaste. The work is based on the FDA method 1 which uses a 30 m x 0.25 mm x 0.25 µm wax column with a 5 m guard and this method evaluates the presence of DEG and

lower levels. The use of analyte protectants in the GC-MS analysis of a group of benzodiazepines was investigated and the results are discussed below. Methods Analytes The following benzodiazepines were analyzed in this work: lorazepam, diazepam, lectopam, nitrazepam, clonazepam. Standards of these analytes were spiked into a matrix. GC-MS System

by GC/IR was 25-50 parts per million (ppm) (weight/volume), which is similar in concentration to what is routinely used for GC/MS work. Saturation and overloading of the GC/IR instrument occurred near the 1000 ppm level for the two compounds. Our work did not include determination of saturation or an overload point for the GC/MS.

Headspace GC–MS is the most commonly used technique for volatile organic extractables. Some representative starting conditions are given in Table 13.5 . Analyzing the sample neat directly from the headspace vial following an oven incubation as part of the instrument method will usually yield a higher level of extractables than analyzing

(SCD). Another common GC detector is the mass spectrometer. Mass spectrometry (MS) is a technique that is used to elucidate molecular mass and molecular structure for compound identification and/or quantification. While MS can be done without GC separation, interpretation of the data becomes increasingly more difficult when analyzing mixtures

Testing conducted on vial as well as cap/septum. Testing is conducted using common lab scenarios with documented protocols. GC/MS testing uses an Aijiren GC/single quadrupole MSD extracted with iso-octane. LC/MS testing uses an Aijiren LC/single quadrupole MSD extracted with a mixture of acetonitrile and water.
