story
“After the disaster of 9/11, Diazald
®
, a highly explosive compound used in herbicide analysis, was immediately controlled by theU.S.
government whichmade shipment impossible. Restekwas instrumental in helpingme to develop an isocraticHPLCmethod that did
not require the use of Diazald
®
.Thismethod is not only safer, but it saves us time andmoney.Thanks, Restek!”

UltraCyanoColumns (USPL10)
ChromatographicProperties:
High-purity cyanophasewith few silanol sites.Often a better choice thanC18phases for basic pharmaceuticals,
especially regardingpeak shape and selectivity.Cyanophases aremore rugged thanbare silica for normal phase
analyses because they are less sensitive to small amounts of water in themobile phase.
