Sample digestion
60 minDigest the sample by microwave or wet digestion into a clear solution
💡 Tip HNO₃–H₂O₂ system is common
⚠️ Caution Work in fume hood to avoid acid fumes
🧪 Materials for this step (click to shop by spec/brand)
2
Calibration curve
30 minDilute metal stock standards into a calibration series
💡 Tip Add matrix modifier to reduce interference
⚠️ Caution Match standard matrix with the sample

3
Instrument setup & ignition
30 minInstall hollow cathode lamp; tune flame or graphite furnace parameters and ignite
💡 Tip Flame suits mg/L; graphite furnace suits μg/L
⚠️ Caution Ventilate to avoid flashback risk

4
Sample measurement
40 minMeasure absorbance of blank, standards and samples in sequence
💡 Tip Subtract blank for each batch
⚠️ Caution Dilute high samples within linear range

5
Quant & report
30 minCalculate sample metal concentration from the calibration curve with QC
💡 Tip Use spike recovery to assess accuracy
⚠️ Caution Keep units consistent with dilution factor

⚠️ 5 Common Beginner Mistakes
- ① Incomplete digestion causing low results
- ② Unremoved matrix interference
- ③ Improper flame parameters lowering sensitivity
- ④ Blank contamination raising background
- ⑤ Standard matrix mismatching the sample
❓ FAQ
+AAS or ICP-MS?
Use AAS for routine; ICP-MS for multi-element trace.
+Notes for mercury?
Use cold vapor/hydride generation to avoid volatility loss.
+Dilute samples?
Dilute to fall within the linear range.
