YYJ Waste Gas Collection Device
I.Introductions:
The collection device is specially designed for the digestion furnace acid gas collection device,
which can collect a large amount of acid gas (acid mist) generated during the sample digestion
process through the collection device, and then through the negative pressure device or
neutralization device for treatment.

YY-1B Acid & Base Neutralization Device
I.Introduction:
The sample digestion process will produce a lot of acid fog, which will cause serious pollution
to the environment and damage the facilities. This device is the best instrument for collecting,
neutralizing and filtering acid fog. It consists of three filters. The first stage is neutralized and filtered
by the corresponding concentration of alkali solution into the second stage, and the second
stage uses distilled water to continue to filter the residual waste gas entering the first stage into
the third stage buffer, and the gas after the third stage filtration can be discharged according
to the standard without causing harm to the environment and facilities, and finally achieve
pollution-free emission

YY9870B Automatic Kjeldahl nitrogen analyzer
Summary:
Kjeldahl method is a classical method for nitrogen determination. Kjeldahl method is widely used to determine nitrogen compounds in soil, food, animal husbandry, agricultural products, feed and
other products. The sample determination by this method requires three processes: sample
digestion, distillation separation and titration analysis
The company is one of the founding units of the national standard of “GB/T 33862-2017
full (semi-) automatic Kjeldahl nitrogen analyzer”, so the products developed and produced by
Kjeldahl nitrogen analyzer meet the “GB” standard and related international standards.
