Thoughts on new barrier discharge ionization detector

[taylorb]

Shimadzu has just started selling a GC with the new barrier discharge ionization detector.
It is universal and has 100 times the sensitivity of a TCD and 2 times the sensitivity of a FID.
Will these both be obsolete in the next ten years.
It also does not deteriorate over time.
Check out this video.

This could be a huge advancement for GC.
The only potential problem I see is that it uses helium.
Thoughts please.

How is it different from a pulsed-discharge helium-ionization detector? Both are attractive detectors (except for the helium problem that you mentioned).

Hmmm does not look that different. You can get Argon ionisation detectors too

With PDID you really need to heartcut out the matrix peak - do you still need to do that with BDID? If not that would be a big advantage.

You can get Argon or Helium emission plasma detector with LDetek. Please have a look at

http://www.ldetek.com/our-products/plasmadetek-2

This detector has the ability to detect from ppb to percent using either argon or helium as carrier gas.

Don't hesitate to contact us at dgagne@ldetek.com if you have any question.

One more benefit of the LDetek (PED) over the standard ionization detector.
The LDetek plasma emission detector can be configured as a selective detector comparing to standard ionization detector which are sensitive to everything.
Its emission mode makes the Plasmadetek being able to be selective to the desired impurities and block the matrix gas. Up to 4 optic detectors can be mounted on the same plasma source. Each of the detector can be configured for the desired impurities to be measured or be generic.
