Advantages of DW-AFS310 AAS

  1. Stable Injection System: Dual peristaltic-pump intermittent flow injection ensures stable sample delivery, simple operation, easy maintenance and long service life.
  2. Real-Time Flame Monitoring: Automatically monitors the flame status in real time without manual observation, reducing external interference during measurement.
  3. Automatic Gas Flow Control: Dual mass flow controllers provide fast, stable gas regulation with accuracy up to 1 mL/min, plus abnormal-condition diagnosis and automatic gas shut-off when idle.
  4. Intelligent Hollow Cathode Lamp: Automatically identifies the element lamp type and factory number, records lamp operating life and provides working-status information.
  5. Dual-Channel Detection: Supports simultaneous analysis of two elements, with single-channel enhancement for improved sensitivity and lower detection limits.
  6. Simplified Calibration & Automation: Only the highest-concentration standard solution is required to generate the calibration curve, with automatic high-concentration sample dilution and pipeline cleaning.
  7. Efficient Gas-Liquid Separation: Secondary gas-liquid separation minimizes the influence of water vapor on analytical results, improving measurement reliability.
  8. Intelligent Operating Software: Chinese/English Windows software supports automatic qualitative and quantitative analysis, sample-content calculation and report generation.

FAQ

The DW-AFS310 supports Hg, As, Sb, Bi, Se, Te, Cd, Ge, Pb, Sn and Zn, covering 11 trace-element applications.

Typical samples include water, wastewater, food, grains, agricultural products, soil, fertilizers, feed, pharmaceutical materials, cosmetics, ores, minerals and other properly prepared laboratory samples.

Yes. Most solid and complex samples require suitable pretreatment or digestion before analysis. The appropriate procedure depends on the sample matrix, target element and analytical standard.

Yes. The system supports automatic dilution of high-concentration samples.

Yes. Automatic pipeline cleaning is available to simplify routine operation and help reduce sample carryover.

The instrument uses dual mass flow controllers with gas-flow control accuracy up to 1 mL/min. It also provides abnormal-condition diagnosis and automatic gas shut-off when the system is not working.

Send Drawell your sample type, target element, expected concentration range and required analytical standard. The technical team can then recommend the appropriate analytical configuration and sample-preparation solution.
