In experiments such as environmental testing, food analysis, and metal element analysis, sample digestion and acid treatment are crucial steps in the pretreatment process. The traditional method of acid removal often relies on manual labor or simple heating, which not only has low efficiency and high risk, but also easily causes problems such as acid mist diffusion and sample loss.

With the continuous improvement of laboratory requirements for efficiency, completeness, and controllability, acid rushing instruments have emerged and become an indispensable pre-treatment auxiliary equipment in modern laboratories.

1、 What is an acid rush machine?

Shanghai Yetuo Acid Removal Instrument, also known as Acid Evaporator, Digestion Acid Removal Instrument, Intelligent Acid Removal Instrument, is a laboratory equipment used to evaporate excess acids (such as nitric acid, hydrochloric acid, aqua regia, etc.) from samples under controlled conditions.

This device usually integrates a heating and temperature control system, exhaust and acid guiding system, sample grade design, and anti-corrosion structure. It can be used for acid removal operations before heavy metal or inorganic element analysis by ICP, AAS, ICP-MS, etc., improving data stability, reducing matrix interference, and extending the service life of analytical instruments.

2、 Core functions and advantages

Gao effect heating, fast acid removal

The device supports uniform temperature control heating, which can heat the sample to the set temperature (usually between 80 ℃~240 ℃), accelerate the evaporation rate of acid, and improve the efficiency of sample processing.

Closed acid drainage system, an all ring system

Most acid detectors are equipped with acid caps and acid mist collection systems. External ventilation equipment can prevent the spread of acid mist in the laboratory, ensuring the safety of personnel and meeting environmental requirements.

Multi channel design, batch processing

Common models support 9-bit, 12 bit, 24 bit and other sample channels, which can process multiple samples at once, improve experimental throughput, and meet the daily large-scale processing needs of laboratories.

Corrosion resistant material, long service life

The inner cavity and air guiding components are often made of PTFE (polytetrafluoroethylene) or high borosilicate glass, graphite spray coating materials, which are resistant to strong acid and alkali corrosion and easy to maintain.

Intelligent temperature control, automated operation

Equipped with functions such as digital temperature control, time setting, and over temperature protection, it achieves precise temperature control and automatic operation, simplifies the operation process, and reduces human error.

3、 Widely applicable scenarios

The Shanghai Yetuo acid analyzer is widely used in the following experiments and industries:

Environmental monitoring station: sample treatment before heavy metal analysis in soil and water quality;

Food and drug testing: After sample digestion, remove excess nitric acid, aqua regia, etc;

Metallurgical/Mineral Analysis: Acid removal from metal ore samples for subsequent ICP analysis;

Research institutions and university laboratories: conventional element analysis, sample pretreatment;

Third party testing agency: Batch sample preprocessing to improve efficiency and data quality.

4、 Typical application process

Sample pre digestion (using microwave digestion, electric heating plate, etc.);

Add a quantitative acid solution (such as nitric acid) to further decompose the residue;

Place the sample in the acid analyzer, heat it up and remove excess acid solution;

After the acid rush is completed, the sample can be transferred to a constant volume, diluted, and entered into the analytical instrument.
