ICP-OES Torch Maintenance

Stop ICP-OES Torch Problems Before They Start

Maintain your ICP-OES sensitivity with proper torch maintenance

Torch blockages can reduce sensitivity, degrade accuracy, and even lead to torch damage and melting. They can also result in lost productivity as you identify, locate, and clear the blockage.

Regular torch cleaning and maintenance is critical to preventing these issues. That’s why we created a complimentary Technical Overview: “Simple Steps for Clearing a Blocked Injector in Your ICP-OES Torch.”

NEW ICP-OES Torch Selection Guide

One-piece quartz? Semi-demountable? Dedicated high solids or organics? It’s not always easy to know which torch type you should be using. This guide will help you quickly choose the right torch to suit your application and instrument.

Troubleshooting tips for ICP-OES torches

Problem: Sensitivity loss

Tip: Keep a spare torch handy so you can simply change the torch and restart analysis immediately, while you remove the blockage.

Solution:

To minimize carbon deposition, select the right sample introduction system, use the optimum parameters for organic solvents, and introduce oxygen as option gas.

  • Shut down the plasma
  • Remove and clean/replace the torch
  • Restart your analysis
  • Use a double-pass spray chamber
  • Select a nebulizer that produces a fine aerosol
  • Choose an “organics” torch, which has a narrower bore injector
  • Use narrow-bore peristaltic pump tubing, so less sample is introduced into the plasma

Problem: Samples with high total dissolved solids (TDS)

Solution:

To minimize blockages, ensure you’re using the right sample introduction system and use the optimum parameters for high-TDS samples.

  • Use a double-pass spray chamber
  • Select a nebulizer that is resistant to blockage
  • Choose a “high solids” torch, which has a wider bore injector
  • Use narrow-bore peristaltic pump tubing, so less sample is introduced into the plasma
