Sample Preparation:

Sampleprep ID:	SP002348
Sampleprep Summary:	Frozen serum samples were thawed on ice. For preparation of the serum, a 50 µL sample was extracted using 1 mL of N2-degassed 1st extraction solution. Then, the samples were mixed for 10 min and centrifuged for 10 min at 18945 RCF and 4°C. The supernatant was dried for 6 hours at 45°C. The dried samples were re-extracted with 2nd extraction solution. Then, the extracted samples were redried for 8 hours under the same conditions used in the first extraction step. The dried samples were derivatized with methoxyamine at 30°C for 90 min and subsequently trimethylsilylated with a mixture of fatty acid methyl ester, which is used for the retention time index, in N-methyl-N-(trimethylsilyl)-trifluoroacetamide at 70°C for 45 min.
