Transfer a sample of the peptide fractions or reaction controls into an HPLC vial and dissolve it in a mixture of 0.1% TFA in MeCN/H2O (1:1, 300-500 µL). Place the HPLC vial into the autosampler of the analytical RP HPLC. Inject 250 µL of each sample. Use a 2
Fast HPLC-DAD quantif ication procedure for selected sulfonamids, metronidazole and chloramphenicol in wastewaters using second-order calibration based on MCR-ALS, Talanta. 113 , 68– 75.
In the GC vial, mix four parts HPLC grade acetic acid for every one part sample (For example, use 36 µl sample and 144 µl acetic acid.) Put the vial on a gas chromatograph auto sampler for analysis.

2010/3/1 · 2.2. ChemicalsAFB1, B2, G1 and G2 standards were purchased from Supelco (USA). Solvents were of the highest purity available commercially. All other chemicals used were of analytical grade. Stock solutions of all AFs with concentrations of 60 ng/ml were prepared in HPLC grade methanol:water (50:50, v/v) and kept in secured conditions at −20 C in the darkness.
Limit the pressure in your columns to 5,000 psi and avoid rapid changes such as manual injectors that “slam” the pressure. For this and other reasons, it is best to operate your HPLC system with pressure cut off around 3,500 psi. This will protect your columns
