HJ 544-2016 "Determination of Sulfuric Acid Mist in Waste Gas from Fixed Pollution Sources - Ion Chromatography Method"

GB/T 16157-1996 Determination of particulate matter and sampling method for gaseous pollutants in exhaust gas from fixed sources

2Method principle

Use glass fiber (or quartz fiber filter cartridge) in series with an absorption bottle containing 250ml of absorption solution to collect sulfuric acid mist samples from organized exhaust gas. After pre-treatment, the collected samples are separated and measured for sulfate ions using an ion chromatograph. Qualitative analysis is performed based on retention time, and peak area or peak height is quantified.

3main features

1) The waste gas sulfuric acid mist sampling gun is used for collecting and measuring sulfuric acid mist in fixed pollution source waste gas, and can be used in conjunction with smoke and dust samplers.

2) Collect sulfuric acid mist samples from organized exhaust gas by connecting a glass fiber filter (or quartz fiber filter) in series with an absorption bottle containing 250mL of absorption solution. After pre-treatment, the collected samples were separated and measured for sulfate ions using an ion chromatograph.

3) Automatic temperature control heating, no need for staff settings, meets relevant sampling temperature requirements

4)Sampling tubeThe S-shaped pitot tube and platinum resistor are integrated in design, and the whole machine is designed in a modular manner, which can measure the flow rate and temperature of flue gas while sampling, making it lightweight and portable.

5) Heating the front section of the filter cartridge effectively removes moisture and improves sampling accuracy.

6) The sampling gun is heated throughout the entire process, and the rear end is condensed in an ice bath.

7) Equipped with a series of sampling nozzles, suitable for collecting at different flow rates.

8) The pipeline and sampling nozzle are made of high-quality stainless steel, which is convenient to use, corrosion-resistant, and easy to carry.
