Test Method:

The DEHA CHEMets® Test Kit (0-400 & 400-3000 ppb) employs the PDTS chemistry. The sample is treated with an excess of ferric iron. DEHA (N,N-Diethylhydroxylamine) reacts quantitatively with ferric iron by reducing it to the ferrous state. The resulting ferrous iron then reacts with PDTS (3-(2-pyridyl)-5,6-bis(4-phenylsulfonic acid)-1,2,4-triazine disodium salt) to form a pink-purple colored complex in direct proportion to the DEHA concentration.

"Just a note to let you know that your team did a great job of getting an order in the system late yesterday afternoon. We needed ATP swabs to assist a customer, and they had to ship same day for the meeting. Not sure if the customer service team uses track shoes or rollerblades, but they are simply great!"
