GC-C: We utilize a GC-MS for assistance with compound identification, retention times, and methods development. Samples should be in 2 mL screw top vials (12×32 mm) with 8mm diameter septa caps. In the event of small samples, vial inserts can be used. All derivation of samples is to be performed by the client. Derivation with methlyboronic acid (MBA) or trimethylsilyl (TMS) is recommended. Due to the specificity and time requirement for these analyses, availability is typically limited to internal clients only. Contact the lab manager for details.
