Methods:The content of menthol in erting oil was determined by capillary gas chromatography using a ECTM-WAX capillary column(30 m×530 μm,1.2 μm),and methyl salicylate was adopted as internal standard.
A capillary GC method for the determination of the materials and products in the preparation of chlorobenzaldehyde from benzaldehyde was introduced. The range of linearity were 7.3～130.3mg for benzaldehyde and 10.7～168.2mg for chlorobenzaldehyde, with correlation coefficient 0.9990 over, RSD less than 1.5% and the recovery 99.5%～101.3%.
A capillary GC method with FID detector for the determination of residual organic solvents methanol,acetone, acetonitrile, tetrachloromethane and 1,2-dichloroethane in arbidol hydrochloride was established.
Methods: Concentration of valproic acid in serum of epileptic children was detected by Capillary column gas chromatography with a rising column temperature program, and the relationships between serum concentration, clinical effects, adverse reaction and quality of their life were analyzed.
The milk sample was homogenized with acetone and acetonitrile(V∶V=1∶1), centrifuged. The extract was purified on a C_(18 )cartridge, collected and evaporated to dryness. The 14 pesticides were separated from the GC-ECD by capillary gas chromatographic column.
