An improved GC method for the analysis and quantification of the culture broth with no sample pretreatment prior to GC analysis is described; the method also includes a lower limit of detection, less time and a wider linear range.

Flat Bottom Headspace Crimp Top Glass Vials (100/Pk) Flat bottom Headspace, 20 mL, 23 x 75 mm Flat bottom Headspace, 10 mL, 23 x 46 mm Part No. P/N , . Rounded Bottom Headspace Crimp Top Glass Vials 20 mm beveled crimp top creates a much tighter seal than flat crimp surface. Designed for Perkin-Elmer.

The oils were dried over anhydrous Na 2 SO 4, followed by filtering, and stored at 4 °C in sealed glass vials for further use. 2.4. GC-MS analysis. The oils were subjected to GC-MS using a flame ionization detector (FID) and an HP-5MS capillary column (length = 30 m, i. d. = 0.25 mm, thickness = 0.25 m).

For our range of Clarus GC systems we offer a full suite of instrument and laboratory consumables. Ferrules, gas filters, inlet septa and liners coupled with an extensive range of GC columns are complemented by every items, such as vials, caps and standards.
