1. Product introduction

Cold atomic absorption mercury detector is a new intelligent mercury detector introduced by our company. Cold atomic absorption method, based on elemental mercury at room temperature, can be volatilized into mercury vapor without heating, and has a strong absorption effect on ultraviolet rays with a wavelength of 253.7nm. Within a certain range, the concentration and absorption value of mercury proportional to Beer's law. Directly measure the mercury content and directly read the measured concentration. This instrument is suitable for environmental monitoring, tap water, chemical industry and other industries to measure the mercury content in water, air, soil, food, cosmetics, and chemical raw materials.

2.product parameters

1. measurement principle: cold atomic absorption method.
2. Automatically calculate and directly read the concentration of mercury without user conversion.
3. Measuring range: 0-10ng/ml (when it is higher than 10ng/ml, it can be measured by dilution).
4. Lower limit of detection: 0.2ng/ml
5. Linear correlation coefficient: R≥0.995
