Converting ppm channels to weight % oxide

Discussion for note.

Hi, I would like to enter our internal standards as wt% oxide. Is this possible? For example SiO2 in BCR-2G is 54.4%, (from GeoRem) and our probe also gives major elements as oxides. Can't we use these without having to convert them? Any pointers would be appreciated.

Hi JasonDay

We'll add this in an upcoming release, as you cannot automatically convert from oxide to elemental concentrations for Int Stds at the moment. I'll post here when it's available.

Kind regards,
Bence

Hi @Bence,

Does the "wtpc_oxide" under units in the internal standards section in the 3D trace elements DRM not do this?

Thanks,
Cole

Thanks Bence and mcolebishop for this, both very helpful. I will have a go with 3D Trace Elements DRS in the meantime. And yes, I was referring to the old school Trace Elements DRS ;-) Best regards.

Bence

Sorry, I should have been more specific: 3D Trace Elements has a wt%_oxide option, but I assume the original question was about the older Trace Elements DRS. That's where we'll be adding the option.

Kind regards,
Bence
