response are excellent for the very active compounds endrin, DDT, and

methoxychlor, peaks 89, 95, and 102, respectively.

Low-bleed Rtx

-5Sil MS columns ensure low detection limits and excellent instru-

ment stability in semivolatiles analysis.

We incorporate 106 Method 525.2 target compounds in six new, stable mixtures.

The concentration of each component in these mixes, 1000µg/mL,

is consider-

ably higher than in mixes from other sources, and significantly more analyses can

be conducted from each ampul of material. We have formulated the new calibra-

tion mixes by chemical class: semivolatiles, PCB congeners, organochlorine pesti-

cides, nitrogen/phosphorous pesticides.

Pentachlorophenol is included in the

semivolatiles mix at a concentration four times higher than the other analytes, as

required by the method. For the convenience of our customers we include hep-

tachlor epoxide isomer A, an analyte not on the target list for Method 525.2, in

Chlorinated Pesticides Mix #2. Six of the nitrogen/phosphorous pesticide analytes

on the target list are unstable in aqueous matrices; we combine these analytes in

a separate mix (cat.# 32423). We do not include two compounds, disulfoton sul-

foxide and disulfoton sulfone, in either our new mixes or our existing mixes. In

water, disulfoton is rapidly oxidized by chemical reaction to the analogous sulfox-

ide and sulfone. Consequently, the sulfoxide and sulfone cannot be included in the

mix with disulfoton. We offer individual solutions of the two analytes — please

refer to our catalog or web site.

In addition to calibration mixes for Method 525, we also have all needed quality

control standards: internal and surrogate standards, a fortification recovery stan-

dard, and a GC/MS performance check standard. New Method 525.2 Surrogate

Standards Mix includes optional pyrene-d10. All new mixes are described on page 3.
