Jasco, not the most well known but probably the best HPLC instrument I have used.
Analyze active ingredients in FDA products
The Jasco system is rugged and easy to use. The software is very user friendly unlike many other platforms I have worked on. Customer service is always quick to respond either on the phone or in house if needed.

Analysis of polystyrene oligomers by semi-micro GPC
In this report, JASCO shows polystyrene oligomer analysis using a GPC column designed for high-performance analysis. Analysis using the LC-4000 Series RHPLC system results in a 30% solvent saving compared to conventional separations.
Analysis of parabens using UHPLC
Parabens, esters of p-hydroxybenzoic acid, are used as preservatives in cosmetics and foods. In this application note, JASCO demonstrates how UHPLC can be applied to provide a high throughput method to determine the content of esters.
Analysis of Protein Hydrolysate Amino Acids using OPA Post-column Derivatization by Quaternary Low Pressure Gradient System
Amino acid analysis has been applied to several categories such as food, medicine, protein science and metabolome study, and is an important measurement technique. An amino acid analysis system using a low pressure gradient unit with OPA post column derivatization provides excellent repeatability and good separation in a short analysis time. The analysis results of food analysis and amino acid composition analysis of protein using this amino acid analysis system are reported.
Analysis of Dabsyl Amino Acids using HPLC
The pre-column derivatization using HPLC for amino acids analysis has prevailed as a simultaneous separation method of multiple components using a selective, high-sensitivity detector and a reversed phase column. Many results of amino acids analysis using dabsyl chloride as a reagent for pre-column derivatization have been reported because the amino acids derivatized by dabsyl chloride are more stable than those by other derivatization agents. Also a simply a UV/VIS detector can be used with high sensitivity. This application note demonstrates the measurement of the standard mixture of amino acids.
