FAQ - Frequently Asked Questions

The glassware inside the ICP stand must sometimes be cleaned or replaced.
WARNING: There is a risk of burn injury. Do NOT touch the plasma stand interior for 3 minutes after the plasma is extinguished.

CAUTION: The glassware is fragile. Handle it with care.

 

1. Torch
  Replace the torch in the following cases.
  • If the torch melts (periphery)
  • If samples adhere to the torch's center orifice
  • If, after analyzing high-concentration boron (B), a trace amount of another element is to be analyzed
  • If the torch's center orifice melts or is damaged in some other way
  NOTE: Even if the internal diameter of the tip of the torch's center orifice becomes smaller, this cannot be checked with the torch installed. If the spectra for an element do NOT appear or if the intensity weakens, it is possible that the tip of the torch's center orifice has melted or the internal diameter has changed.
    Remove the torch and check the tip of the torch's center orifice.

 

2. Nebulizer
  Deposits adhere to the tip of the nebulizer when analyzing high salt sample. Be sure to use a water bubbler (option) when analyzing this kind of sample. If there is clogging in the tip of the nebulizer, the sample suction speed may reduce significantly and sample suction may even stop. In this case, the nebulizer must be replaced or cleaned.

 

3. Chamber
  Replace the chamber in the following cases.

  • If a conspicuous amount of dirt accumulates
  • If there is a crack or some other damage that causes gas to leak and adversely affect operation

 

4. Cleaning Glassware
  Clean the glassware with hydrochloric acid (HCl) 2 standard solution.
  NOTE: Do NOT perform ultrasonic cleaning on the glassware.
