Glass Expansion ICP-MS Cones

(In response to NexION 5000 cones) We have been able to test the cones and so far, have been able to determine a performance that corresponds to the original cones, especially in terms of oxide rate, sensitivity, etc.

We had higher sensitivity due to using the new Pt cones we just ordered from GE.

Thank you so much for repairing our 2 skimmer cones. I was so happy when I received those two repaired skimmers, shiny like brand new. Thank you!! Everyone in the lab actually impressed by the work and this service. We all think this service deserve a star, and a thanks card.

We've tested the GE sampler cone on all three of our Helios™ instruments and it worked great, showing highly comparable performance to our current Fluidigm ® cone using both QC beads and biological cell samples. The QC bead CVs were actually slightly higher than with our Fluidigm ® cones, but this could admittedly just be because it was a brand new cone and our current cones have likely been used for a while.

Tested out your GE sampler cone, looks good! Primarily we look at the Tb mean duals in the tuning solution and polystyrene eq beads.

(In response to GE P/N TG1045-Ni) Consensus is they really like this cone. There's a general issue with the inserts performing poorly on the standard cones if they are not perfectly nested. We then, when encountering issues with doubly charged/oxides/rsd/sensitivity etc, have to troubleshoot the problem and occasionally it's the insert. This eliminates that as a potential point of failure. We've seen no negative issues. It's very durable. We've been running it now for over 2 months. We have the plasma lit for 12-18hrs per day nearly 7 days a week. This would definitely be a piece of hardware we'd look to use as a substitute for our skimmer+insert cones.

We use tons of GE stuff in our lab. I am very satisfied with everything, especially the ICP-MS cones we recently purchased. Keep up the great work!

I tried the new cone on our worse Helios™ (Helios™ A) which usually has a Tb that doesn’t get much above 1.0 million and with this cone I got a Tb of 1.48 million!

We have been running your sampler cone in our brand new Helios™ instrument. The initial comparison I sent previously showed they were nearly identical in terms of performance for an n=1, (both cones were new).
