PhysicalCharacteristics:
*For post-column derivatization / fluorescence detection appli-
cations for a 4.6mm ID column the total system dead volume,
including the post-column reactor, must be less than 650µL. For
standard post-column reactor systems, we recommend a 250 x
4.6mm, 5µm column. Call Restek technical service formore

Carbamates are widely used insecticides that pose a health risk as endocrine
disruptors.OurUltraCarbamate column, in a 50mm length, separates com-
mon carbamates in less than10minutes (Figure 1), significantly less than the
time required by traditional C18 columns. In addition to the best column
choice for the analysis,weoffer referencemixes forMethod531 carbamates, a
performance check mix, and the specified internal standard, 4-bromo-3,5-
dimethylphenyl-N-methylcarbamate (BDMC).

Simple, SensitiveHPLC/UVAnalysis for Paraquat andDiquat
These highly charged quaternary amines are poorly retained on alkyl stationary phases. Using only
acetonitrile, water, and a solvation-blocking reagent, our separation system alters the interactions
among analyte, mobile phase, and stationary phase, and promotes solubility of the analytes in the
stationary phase. In our system, the detection limit is 6ppb for either herbicide, and the analysis is
completed in less than 10minutes. An optimized solid phase extraction cartridge concentrates the
herbicides for the analysis.
