The new 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.
Chromaster New Features and Improvements:
1. System Performance
Innovative, new 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.
Parabens are widely used in cosmetic and food formulations, yet also are suspected of posing health hazards. As such, it is important to accurately measure the concentration of various parabens present in a product. Presented here is a method for analysis of parabens in hand cream using the highly flexible Hitachi Chromaster HPLC system with diode array detection.
The analysis of cortisone, prednisolone, dexamethasone, hydrocortisone acetate, and testosterone is shown using the highly flexible Chromaster HPLC with UV detection.
Steroids are often used in topical ointments due to their anti-inflammatory and immunosuppressive properties. However, their use may also result in various side effects. As such, it is important to accurately measure the concentration of steroids in topical ointments. Presented here is a method for analysis of steroids in commercially available topical ointments using the highly flexible Hitachi Chromaster HPLC system with UV-vis detection.
