Sample Submission

Sample Preparation Guidelines

ESI/APCI-MS Analysis

Sample must be prepared at ~ 0.1-1.0 mg/ml with a sample volume of ~0.05-0.1 ml using MeOH, ACN, or H2O. Avoid salts, DMSO and DMF, buffers, stabilizers and detergents.

GC-MS Analysis

Sample concentrations should be ~0.1-0.5 mg/ml. NEVER exceed a concentration of 1.0 mg/ml, if you do you can damage the GC column or the MS components.

Samples must be prepared in most volatile organic solvents, preferably acetone, methanol, hexane, aromatics, and alkanes. Less preferable are halogenated solvents (e.g. chloroform, methylene chloride, etc.) and ethers (e.g. diethylether, THF). DO NOT use water, DMF, or DMSO as a solvent. Place your sample in a GC-MS specified sample vial with the correct septum and cap, i.e. Agilent Part Number 5182-0714 (Pack of 100 screw top vials) and Agilent Part Number 5182-0717 (Pack of 100 Blue screw caps and PTFE/red rubber septas). Sample must fill at least half of the vial volume.

High Resolution MS Analysis

HR-ESI/APCI-MS analysis: Please provide at least 10 ug neat compound or prepare the sample at ~ 0.1-1.0 mg/ml with a volume of ~0.05-0.1 ml using MeOH, ACN, H2O, Acetone, or DCM. Avoid salts, DMSO and DMF, buffers, stabilizers and detergents.
