Microengineered open tubular columns for GC analysis. NASA Astrophysics Data System (ADS) Wiranto, Goib; Haskard, Malcolm R.; Mulcahy, Dennis E.; Davey, David E
Using chiral b-dex column and commercial R-oxide-styrene patterns for separation of epoxides in GC, 2 peaks are shown, the stationary phase is 2,3-di-O-methyl-6-0-TBDMS-β-cyclodextrin, The
GL Sciences’ economic vials for autosampler can be used on all common autosamplers due to their technical geometry. Using these universally compatible vials, rationalization of other 2 mL vials, as for instance 11 mm crimp neck vials, screw neck vials 8 - 425 and 10 - 425, is possible. 1030-10002 1.5 mL 32 x 11.6 mm Clear Glass 9-425 Thread

Vials and Bottles Filling sample vials 2 Filling sample vials Figure 1 shows the recommended fill volumes for sample vials of: • 1 mL for the 2 mL vial • 50 µL for the 100µL vial The air space in the vial is necessary to avoid forming a vacuum when sample is withdrawn. This could affect reproducibility.

By comparison, detection limits for established GC-MS methods employing derivatization and electron-capture detection vary widely, but common values range 0.2 to 2 pg on-column. Moreover, the described ion molecule reaction is highly selective for C-21 progesterone metabolites over both C-24 bile acids or C-18 estradiol, making the assay both
Prepare the sample diluent by adding 0.2 mL of trifluoroacetic acid (TFA) using a glass gas tight syringe to 100 mL of HPLC grade acetonitrile to form "MeCN+0.2% TFA" solution. Mix well. Prepare the sample solution for HPLC analysis at a concentration of 1mg/mL in "MeCN+0.2% TFA". Using a 5 figure balance, zero a 1.8mL clear HPLC glass vial.
