Demonstrate a GC-MS method for identifying phencyclidine. An extraction procedure for this compound was optimized on a Servo+ PCP SPE cartridge. A urine sample was spiked with phencyclidine and analyzed by GC-MS using a Tra ceGOLD TG-5MS column.

1 GC Derivatization Pierce 2003-2004 Applications Handbook & Catalog Derivatization The chemical literature contains an abundance of data on derivatization, most of which is relevant to particular compounds, classes of compounds and derivatization reagents.

13/5/2011 · A GC‐MS based liquid injection method was developed to determine free analytical levels of guaiacol and 4‐methylguaiacol after acid hydrolysis of purified precursors of taint compounds. The optimised conditions for releasing the free form of guaiacol and 4‐methylguaiacol were hydrolysis with 2.5 M H 2 SO 4 (pH 1.0) at 100°C for 30 min ( Figure 2 ).

Sample Preparation Benzo[j]fluoranthene and benzo[e]pyrene were added to a 16 PAH mix according to US EPA Method 610 at a concentration of 10 µg/mL. The standard was prepared in hexane for GC-MS analysis. GC-MS Conditions GC: Thermo

In an attempt to discriminate and identify several bacterial species, headspace air samples above a series of bacterial cultures were interrogated using a TD-GC/MS system. Three microorganism strains with relatively low pathogenic character – Escherichia coli, Bacillus subtilis and Staphylococcus aureus – were investigated during a period of 72 hours from the inoculation.

13/4/2021 · Metabolic analysis using GC-MS has been performed once on X. laevis oocytes, however the aim was to conduct high sensitivity metabolomics from minimal sample volumes (Koek et al., 2010). Xenopus oocytes have also been utilized to reconstitute conserved multicellular signaling pathways by introducing a minimal number of exogenous membrane components ( Vera and Rosen, 1990 ).
