Dear Dr. Nick Collins
I'm Hiroto Kawashima of assistant professor from Akita prefectural university of
Japan. Now, I try to research source apportionment of suspended particle matter
(PM2.5 , PM10 etc.) and VOCs in air and pesticide in soil using carbon and nitrogen
and hydrogen isotope. I have a question. Could you tell me.
I have a GC/C/IRMS(Isoprime). But the oxidation furnaces(quartz tube, 600mm * 6mm OD
* 0.65mm ID with CuO) can't be used after approximately 200 samples(especially
pesticide). The quartz tube is too expensive. I want to purchase quartz tube (ceramic
tube?), CuO each and hand-made packing.
You use to pack your combustion tube? After how many samples do you analyze, you
exchange the tube? Please tell me information of the oxidation furnaces of Isoprime
