Specpure® calibration standards, designed specifically for the analysis of chlorine in petroleum products by X-ray fluorescence spectrometry.

These standards are made up on a weight/weight basis using balances which are routinely calibrated using NIST-traceable weights. The matrix oil for these standards is a 75cSt mineral oil. All Specpure® standards are accompanied by a Certificate of Analysis which states the actual concentration and the traceability to NIST.

The standards are guaranteed to be stable for one year from the ship date, provided they are kept tightly capped and stored under normal laboratory conditions.
