Restek® innovation!

Xylene-Free, Highly Purified Chloroprene Standard

The R&D chemists at Restek developed a novel procedure that

produces a pure, quantitative chloroprene solution specially stabilized

in purge-and-trap grade methanol. The entire procedure is performed

under carefully monitored conditions to prevent any contamination or

polymerization of the highly reactive, neat chloroprene. The final

solution is specially stabilized, allowing analysts to make dilutions for

working standards in unmodified purge-and-trap grade methanol.

Note:

Because chloroprene is not analyzed by many laboratories, it is

not included in our 8240 VOA mixes. Chloroprene is included in our

8260B MegaMix® calibration mix. Refer to
