HG-310 is a mercury analyzer that addresses highly sensitive measurement with small amount of sample, reduction of reagent consumption and simplified maintenance by new design of the optical system and optimization of the measurement path.
A large LCD screen displays real-time absorbance curve, calibration plot and method parameters, which brings improved user interfaces.
A sophisticated software provides the function to handle various convenient files such as measurement condition files and result files, GLP function. RS-232C interface with optional data acquisition software allows edit and reevaluation of data on your PC. From wide range of system line up and accessories, you can select a most suitable model for your purpose, and future upgrades.
Features
- High sensitivity of lower detection down to 1 ppt Thanks to the newly designed optical system and improved measurement path, it delivers a high sensitivity of 1/500 of MCL (0.0005mg/L) the world.s most strict Japanese environmental guideline.
- Reduced sample and reagent consumption. Smaller sample and reagent consumption also reduces waste and consequently reduces the cost of your laboratory by a factor of four.
- GLP compliant function offers system maintenance information such as total time of mercury lamp in use, accumulated dispense volume from the dispenser, and alerting low reagent remain.
- Equipped with RS-232C interface, edit and reevaluation of data is possible on your PC (optional data acquisition software is required). In addition, data can be transferred to the HITACHI Polarized Zeeman Atomic Absorption spectrophotometer Z-5000 Series and it supports the management of AAS system.
