Eluent prep
20 minPrepare carbonate/hydroxide eluent and degas
💡 Tip Hydroxide systems need online generation
⚠️ Caution Use ultrapure water to avoid ion contamination

2
Column install & equilibrate
30 minInstall guard and analytical columns; equilibrate with eluent until baseline is stable
💡 Tip Equilibrate for 20-30 min
⚠️ Caution Avoid eluent flow interruption

3
Standard & sample prep
30 minPrepare anion/cation standard series; dilute and filter samples before injection
💡 Tip Dilute high-concentration samples first
⚠️ Caution Filter samples through 0.22 μm

4
Injection & detection
30 minInject sample through suppressor and quantify with conductivity detector
💡 Tip Suppressor lowers background for higher sensitivity
⚠️ Caution Keep suppressor wet; avoid bubbles

5
Data & report
30 minIntegrate peaks, quantify via calibration curve and issue a report
💡 Tip Quantify multiple ions simultaneously
⚠️ Caution Verify retention times and ion identity

⚠️ 5 Common Beginner Mistakes
- ① Impure water introducing ion interferences
- ② Unfiltered samples clogging the column
- ③ Eluent concentration drift affecting retention time
- ④ Failed suppressor preventing detection
- ⑤ High-concentration residue contaminating the system
❓ FAQ
+Which ions can be detected?
Common inorganic anions/cations and some organic acids.
+Why unstable baseline?
Often eluent/suppressor issues or air in lines.
+Can anions/cations run together?
Usually need separate anion and cation columns.
