Care of ICP-MS Cones - When to clean

The frequency at which the cones are cleaned depends very much on the application and the workload of the instrument. If the samples are clean and the usage is low, the cones may only need cleaning monthly. But if the instrument is in continuous use and/or the samples contain high levels of dissolved solids or are highly corrosive, the cones may need cleaning daily.

The cones should be cleaned if there are visible deposits near the orifice or if the orifice is blocked or distorted. Deterioration in the performance of the ICP-MS can also indicate that the cones may need cleaning. In particular, watch for increased background signal, memory effects, loss of sensitivity or distorted peak shapes. A change in the instrument vacuum reading can also be an indication of cone problems. If the orifice gets blocked, the vacuum will increase (pressure decrease), although there will usually be a deterioration in performance before this point. If the vacuum decreases (pressure increases), this could indicate that the orifice is worn and has increased in size. If this happens the cone needs to be replaced.

The sampler cone, being exposed to the plasma, will usually need cleaning more often than the skimmer cone. If the performance of the instrument does not recover when the cones are cleaned, then you may need to replace them.

 IKA Tube Mill control

The world’s first patented Tube Mill control is a batch mill with disposable grinding chamber. Eliminates possibility of cross-contamination and the effort of cleaning. The grinding chamber and cover are made of a transparent material so grinding tests can be observed at any time. The mill can be used for hard (Mohs hardness up to 5), dry and brittle materials. During development of the mill, particular emphasis was placed on security. When the grinding chamber is not inserted properly or not closed properly, the drive unit will display an error message and the drive will not start.

  • Programmable and storable test conditions
  • Error Code Display
  • Reproducible test results
  • Easy operation with touch keypad
  • Dust proof sealed housing
  • Quiet operation

Visit the IKA website to learn more about the Tube Mill control.

Perkin Elmer Optima 2100 DV Question
tenemos un icp perkin elmer modelo 2100 y nos da este error. vds out of voltage tolerance windows. me podrian decir como se puede reparar o que hay que comprar para ponerlo a funcionar. gracias
I have an ICP Perkin Elmer 2100 model and gives us this error. "VDS voltage out of tolerance windows". I ask you how this can be repaired and/or what needs to be purchased to make it work. Advise this member

General ICP System Problem with suction
Nebulizer cannot suck up the solution. Air is flowing out of the aspiration tube in the reverse direction instead of the nebulizer sucking. What is the solution? Advise this member.

ICP Purchase Discussion
We are currently in the process of purchasing an ICP and have narrowed our search down to either a Thermo Scientific or Perkin Elmer instrument.  This will be the first ICP for our lab and I would appreciate any input. Join the Discussion
