Analysis of nylon 6 by semi-micro scale GPC
In this report, the measurement of Nylon 6 films and fibers was performed using the LC-4000 Series RHPLC system with RI-4035 refractive index detector designed for use with semi-micro GPC columns offering high performance analysis.

Simultaneous determination of VMA, HVA, and creatinine using HPLC
In this report vanillylmandelic acid (VMA), homovanillic acid (HVA) and creatinine were measured simultaneously by reversed phase HPLC and pre-processing was remarkably improved by HPLC autosampling with a micro-plate. A UV detector was used for creatinine and a coulometric detector (ECD) for VMA and HVA.

Analysis of amino acids and histamine using pre-column derivatization using DABS-Cl
This application note shows an analysis of amino acids and histamine using pre-column derivatization using DABS-Cl.

Analysis of amino acids using pre-column derivatization with DABS-Cl
In this application, a small amount of amino acids of proteins and peptides was quantitatively analyzed by vapor-phase hydrolyzing with hydrochloric acid, derivatizing with DABS-Cl (Dimethylamino azobenzene-sulfonyl chloride) and separated on reversed phase HPLC.

Mass screening for inborn error of amino acid metabolism using HPLC
This report concerns the simultaneous analysis of the anomalous metabolic amino acids of three illnesses.
