Analysis was carried out using a Varian Saturn 2000 GC/MS calibrated using against a 10 µg/g ∆9-THC calibration standard. Instrument performance must be within specification using control standards at both 4 µg/g and 30 µg/g before analysis can proceed. Injection volume was 1 µL. Duplicate injections were made for each analysis.
Glass Bottles and Containers. Glassware is the most common family of lab supplies. Glass Bottles and containers provide the best sample integrity. Glass is inert and thus more chemically compatible than plastic, so the only concern about the chemical resistance of lab glassware is the type of liner inside the cap.
Aijiren 2 mL screw top vials are constructed from from Type 1 borosilicate glass, with low metal content, to protect your sample from destabilizing or leaching. The associated 9 mm screw caps and closures come with your choice of septa constructed from either PTFE silicone or natural red rubber.
These 20 mL vials are manufactured from high density polyethylene. Vials with caps attached are packaged in individual cells in trays of 100. Vials with screw caps packed separately are packaged in polyethylene bags of 100 and placed in a separate tray. Cases of 1000 vials are packed in a single
A 1-mL aliquot of the upper layer was transferred into an Aijiren Bond Elut QuEChERS, fatty samples, AOAC (Aijiren p/n 5982-5122) dispersive SPE 2 mL tube. The dSPE tube was vortexed for 1 min and then centrifuged at 3200 rpm for 3 min to complete the sample extraction. The liquid from the dSPE tube was transferred to a GC vial and run on the

A 0.4 mL sample of this solution was diluted with 0.4 mL of H 2 O for the UPLC-MS/MS analysis. For the GC-MS/MS analysis, 0.4 mL of the solution was dried under N 2 gas and re-dissolved with 0.8 mL of the IS solution; then an AP solution (24 µL) was added before GC injection to obtain good signal and peak shape (Anastassiades et al., 2003
