Headspace gas chromatography offers an efficient sample-preparation technique that can save both time and money in the analysis of VOCs in a number of matrices. Headspace sampling is a separation technique which allows for the extraction of headspace vapor from a sealed sample, with subsequent injection directly into a GC.
a 22-mL headspace vial, heated at 80 C for 45 min and 500 μL of headspace vapor is injected to a split injector of the gas chromatograph. A modification of this method uses only 250 μL of sample, heated to 80 C for 10 minutes. Instrumentation: PerkinElmer®

PerkinElmer releases new gas chromatography products Clarus590 and 690. Analytical Testing Encyclopedia News recently, PerkinElmer announced the launch of the new Clarus 590 and 690 gas chromatography. The product can be used in third-party laboratories, government agencies, corporate quality control and university research departments.
The analysis was performed using a PerkinElmer Clarus®580 gas chromatograph equipped with a capillary column injector and an FID detector coupled to an automatic TurboMatrix™ 40 Headspace sampler. The capillary column used was a PerkinElmer Velocity-1 (30 m, 0.32 mm, 3 um – P/N N9306329). Figure 1.
Gas chromatography was performed using an Autosystem XL gas chromatograph with a flame ionization detector (FID), (Perkin Elmer, Waltham, Massachusetts, USA) with a A/C Nelson 900 interface (Perkin Elmer, Waltham, Massachusetts, USA), an
As mentioned, the procedural mitigations are often manual and paper based. By nature, these procedures are more prone to human error and can create new risks. The FDA encourages companies to ensure that new systems are evaluated for Part 11 before automating as many aspects of data integrity as possible.
This analysis is well suited for headspace sampling because headspace eliminates the sample preparation. The sample is analyzed directly with no need to dissolve the polymer. Multiple headspace extraction (MHE) is a technique to exhaustively extract a sample and calculate the amount of analyte by comparison to an external standard.
