My lab is currently weighing options for upgrading our ICP-MS now that USP <233> is becoming effective. We currently have an ELAN 6100 (no DRC), but since we test a pretty large variety of pharmaceuticals, nutraceuticals, etc., I've made the recommendation that we move towards an ICP-MS with some sort of interference removal technology so that we aren't handicapped by interferences due to sample matrices.
My question is, is there an advantage to having a collision cell over a reaction cell? I'm currently trying to put a proposal together and would like to factor in whether one is a bigger advantage over the other, or possibly even get an ICP-MS with both (e.g. Nexion 300+). We're a very small business and we usually buy generations old used equipment, so buying the shiny, brand-spanking new, top of the line is out of the question.
I was actually leaning towards an ELAN 9000 DRC, but was interested to see if anyone felt going with a NexION 200/300/etc. was worth the extra investment.
Thanks for any help!
