Product Details
CASSulfide analyzer
• Professional sulfide determination
Suitable for liquid and solid samples
• Simple and efficient operation
High precision and accuracy
• Compliant with national standards
Sulfide analyzerprinciple
Sulfide acidification - blowing (aeration) - absorption principle, cyclic absorption method.
1-Release agent bottle; 2-Release agent pipeline; 3-Release agent addition module; 4- Sample bottle;
5-Circulating gas path 1; 6-Absorption bottle; 7-Circulating gas path 2; 8-cycle module; 9-Circulating gas path 3
Simple and efficient
Batch sample cycle absorption for 5 minutes, processing capacity>300 samples/day
• Easy to operate, two key operation
Automatic acid addition to avoid the loss of hydrogen sulfide during manual acid addition process
• Headspace volume<300mL, accelerate circulation blowing and absorption, reduce residue
Safe and energy-saving
The system is sealed and non-volatile, without the need for a fume hood
• No heating required, energy-saving and environmentally friendly
No need for nitrogen, safe and energy-saving
Accurate and reliable
• High fold enrichment, low detection limit
• High measurement repeatability, in compliance with relevant standard requirements
High measurement reproducibility and long-term stable data
carefully designed
Carefully selected materials, inert materials reduce adsorption, reduce cross contamination, and are easy to clean
Scientific design, durable and reliable
meet the standard
