TOSOH AUTOMATED GLYCOHEMOGLOBIN ANALYZER HLC-723® G11 Analyzer
The Tosoh Automated Glycohemoglobin Analyzer HLC-723G11 Variant Analysis Mode is the newest addition to Tosoh’s family of HPLC Analyzers. It has been specifically designed to provide an answer to the ever increasing number of HbA1c requests and general need to optimize laboratory workflows. The G11 is a fast, precise and very user friendly instrument with tons of useful features.
The G11 has a very fast start-up time and daily checks are done in seconds. The analyzing routine only requires one push of a button and is done within 60 seconds in variant mode. Results are shown on the very straightforward high resolution chromatograms. The G11 has automated stop and wash features and a customizable time to power off the unit. Furthermore, columns and filter changes are done in seconds. The HLC-723G11 is a high performance system that ensures smooth operation and trustworthy results.
In addition, the G11 has the flexibility to adapt to the changing needs of modern laboratories by offering the unique opportunity to upgrade from 90 sample loader to 290 sample loader and laboratory automation models.
Representative of a G8 Chromatogram
High Performance Liquid Chromatography, or HPLC, is the gold standard method for hemoglobin A1c testing. Using Tosoh’s proprietary, non-porous column, their ion-exchange methodology provides chromatographic results in high resolution chromatograms without loss of precision.
HPLC, is an analytical chemistry technique to separate, identify, and quantify each component in a mixture. In ion-exchange chromatography, the glycated hemoglobin components are separated according to their different electrical charge. As fractions elute, the time it takes to separate that fraction is called the retention time. The retention times for each fraction determines the identity of the component.
Tosoh’s ion-exchange methodology utilizes a proprietary, in-house developed, non-porous polymer resin column that provides high resolution chromatograms and high efficiency separation without loss of precision. The HbA1c measurement yields direct determination of stable HbA1c through clear separation between labile HbA1c and stable HbA1c by generating a chromatogram that contains key valuable information about the patient including the presence of a hemoglobin variant or hereditary persistence of fetal Hb- a feature unique to the HPLC ion-exchange methodology.
