product overview

The G23 total nitrogen rapid analyzer is a cost-effective water quality testing equipment newly launched by Greencaire in 2019. It adopts sealed catalytic digestion and then uses colorimetric method for measurement. Advanced cold light source, narrowband interference technology, and microcomputer automatic data processing directly display and print the concentration value of the sample.

The device is equipped with a 4.3-inch full-color LCD screen and a flat UI design interface, which allows for a more intuitive display of detection data.

Guided detection mode reduces learning costs and allows users to easily and quickly get started.

The equipment is equipped with pre made reagents, which do not require users to mix multiple detection reagents. Only the water sample for detection needs to be added.

Detection Principle

The G23 total nitrogen rapid analyzer is developed and designed according to the standard of "alkaline persulfate digestion photometry". It uses a closed digestion tube and potassium persulfate as an oxidant to convert all nitrogen-containing compounds in the sample into nitrate at 125 ℃. It then reacts with a color reagent under acidic conditions to form a complex. The absorbance is measured using photometry, and the total nitrogen detection item is selected. The imported cold light source emits a light source signal to the sensor, and the data is processed by a RAM processor to directly feedback the sample concentration value, which is displayed in mg/L.
