16-Hr Laboratory Air Sample with radiello 165
|Column||Raptor C18 (cat.# 9304A65)|
|Dimensions:||150 mm x 4.6 mm ID|
|Particle Size:||2.7 µm|
|Pore Size:||90 Å|
|Sample||Laboratory air sample|
|Diluent:||2 mL acetonitrile extract|
|Inj. Vol.:||5 µL|
|Detector||UV/Vis @ 365, 4.8 nm|
|Instrument||Waters ACQUITY UPLC H-Class|
|Notes||The radiello 165 passive air sampler (RAD165) utilizes a stainless steel net cartridge filled with 2,4-dinitrophenylhydrazine (DNPH) coated Florisil adsorbent. Airborne carbonyls react with the DNPH to form stable hydrazones. The derivatives were subsequently extracted for 30 minutes with 2 mL of acetonitrile. The extract was then analyzed by LC-UV.|
*Mobile phase B was prepared by combining 650 mL methanol and 50 mL acetonitrile.
Printing tips! To print chromatograms full page, change the print settings in the print dialogue window of your PDF reader software: 1) "fit" or "fit to page", 2) "landscape" for wide chromatograms or "portrait" for tall chromatograms.
