We've been running an application that has a TCEP reduction step in sample prep.  On our instruments that run this method we have noticed that the nebulizer needle gets pitted and chipped very quickly.  We end up changing this part every 6-10 weeks depending on our test volume. We have similar or greater test volume on several other instruments with similar preps minus the reducing agent.  We have not noticed abnormal wear and tear on these instruments.  Does anybody else have a similar issue?
