Got a quote from China, they have an XRF which has similar specs to the Bruker, I’m sure it’s not quite as nice, but it’s quite a bit cheaper - quoted as $23,500. Bruker for the Tracer i5 was $38,000.
It looks very similar - columating optics, similar power and ppm resolution, same detector technology, option to manually calibrate a given matrix. I can’t quite tell the difference between their 3 models (3000, 5000, 7000 models), though it seems the 5000 is appropriate. I’ll follow up and ask which is best for the sample types we’re interested in.
Attached is the detailed quote. What do you all think?
More details from LAN scientific. @david.n.forster@DanT hat’s your opinion… what list of elements is more important, what are the required detection limits and precision? I’d like to get Jill’s opinion also.
This database is quite broad and has a lot of samples for the major crops, so it gives us a nice range. It’s unclear if they samples from a wide variety of organic/non-organic/etc etc or if it’s just from grocery stores, so we may have a broader range, we’ll just have to see. But in general, the range was ±50% of the average value.
So this will help direct the discussion, and also we’ll need to buy purified forms of each of these elements to do a standards.
