Hitachi Chromaster HPLC System

The Chromaster analytical HPLC system with ultra-low dwell volume for unparalleled method versatility

Overview

Hitachi Chromaster: HPLC for Today and Tomorrow

The Chromaster HPLC system from Hitachi has established new limits in Performance, Ease of Use, and Robustness. Innovative low-pressure gradient mode, "High Frequent Mode," and Hitachi's proprietary real-time feedback control system greatly suppress liquid pulsation resulting in unparalleled retention time and gradient reproducibility. Additionally, the Chromaster design incorporates an extremely low dwell volume affording the ability to accommodate and transfer methods from a variety of conventional HPLC platforms.

Continued improvements in performance, functionality, and reliability, make Chromaster the perfect HPLC system for any laboratory.

Features

Chromaster New Features and Improvements:

1. System Performance

Innovative, low-pressure gradient mode yields improved peak/gradient retention time. Autosampler adopts a new high precision syringe drive unit for improved accuracy and volume reproducibility. Detectors incorporate ingenuity to improve baseline stability by reducing the influences of ambient temperature change.

2. Ease of Use

The optional GUI (Graphical User Interface) controller offers a high level of visibility, integrated control, and accessibility for automation. Available column management system enables column log data regardless of the column manufacturer. Chromaster maintains full front access operation for user convenience, and built-in common accessories and optimized tubing afford an attractive, space-saving design.

3. Robustness

The Hitachi reputation for instrument reliability continues with the Chromaster, which is made using stronger stainless steel materials and is manufactured with Hitachi's stringent quality control standards.

The amino acid composition of proteins can be determined by hydrolysis of the sample followed by HPLC analysis, which typically includes a derivatization step either pre- or post- column. Here we describe an amino acid analysis method that avoids a derivatization step through use of an evaporative light scattering detector (ELSD) with the Hitachi Chromaster HPLC.

Oxytocin is a peptide consisting of nine amino acids that acts as a neurotransmitter in biological systems. It is known for its roles during and after childbirth, however, it is also the focus of many research projects investigating treatment of disorders such as depression and autism. As such, the concentration of oxytocin found in patient serum is often of interest. Presented here is a method for analysis of oxytocin in serum samples using the Hitachi Chromaster HPLC with diode array detection.

Phytosterols are a class of steroids found in vegetable oils, nuts, and fruits, and are thought to lower cholesterol levels in the blood. Although research remains inconclusive regarding the effect of phytosterols on cardiovascular disease, they continue to be of interest due to their proven cholesterol-lowering ability. Here we describe a method to analyze several phytosterols in pistachios using HPLC with evaporative light scattering detection.
