Blood samples were collected in lithium heparin monovettes<br />
• 500 uL of the sample was diluted with 100 uL 0.1% (v/v) Triton-X-100 solution and<br />
500 uL of the internal standard solution<br />
• This solution was made up to 5 mL with a 0.5% (v/v) NH 4OH solution in a 10 mL<br />
polypropylene autosampler tube<br />
More than 100 samples can be prepared in less than 1hour by one person<br />
