Detail:
Drain Device – Extend fits Shimadzu ICPMS In the context of a Shimadzu Inductively Coupled Plasma (ICP) instrument, the “drain device” typically refers to components involved in the sample introduction system, specifically how waste liquid from the nebulizer and spray chamber is removed. This liquid, which represents the majority of the sample that doesn’t make it into the plasma, must be efficiently drained to ensure stable and reliable analysis

Here’s a breakdown of the Drain Device – Extend – 21-809-4197

• Spray Chamber and Nebulizer Drain:
  • In the sample introduction system, the nebulizer converts the liquid sample into a fine mist.
  • The spray chamber then separates the larger droplets from the mist, allowing only the finest aerosol particles to be carried to the plasma.
  • The larger droplets that are removed from the mist in the spray chamber are then directed to the drain.
• HF Drain Device:
  • For samples containing hydrofluoric acid (HF), a special HF Drain Device is required.
  • This device is designed to be compatible with instruments like the Shimadzu ICPE 9000/9800 and ICPS 7500/8100 ICP-OES and ICPM-2030 ICP-MS.
  • These devices often use fluoropolymer materials and an alumina injector unit to handle the corrosive nature of HF.
• Drain Trap and Tubing:
  • The waste liquid from the spray chamber flows into a drain trap and then through a drain tube to a waste container.
  • The drain trap helps maintain a pressure seal and prevents air from entering the system.
  • Properly connecting and maintaining the drain tube is crucial for efficient waste removal.
• Maintenance:
  • Regularly cleaning the drain trap and drain tube is important for preventing clogging and ensuring smooth operation.
  • Instructions for cleaning often involve rinsing with deionized water and soaking in dilute nitric acid.
  • Check for consistent spray from the nebulizer after cleaning to ensure proper drainage.
