Historically, 2,4-D and Silvex mixtures have com-
prised many herbicide formulations, and we devel-
oped a reference mix for laboratories that analyze
only these two compounds. Similarly, we offer an
individual solution of dalapon, a herbicide not listed
in Method 555, but included in more general
Method 8321A. We offer 1,4-dichlorobenzene as an
internal standard for this assay. All of our new herbi-

Ultra Aqueous C18 HPLC Columns (USP L1)
particle size: 3 or 5µm, spherical; not end-capped; pore size: 100Å; pH range: 2.5 to 7.5; temperature limit: 80°C
cides mixes are prepared in acetonitrile, as appro-
priate for HPLC applications, at a convenient con-
centration of 1000µg/mL.
If your analyses include monitoring chlorophenoxy-
acid herbicides, an Ultra Aqueous C18 column and
our new reference mixes will help you obtain the
most accurate data.

Restek HPLC columns
support environmental
HPLC applications with
rapid analysis times
and effective resolu-
tion of target analytes. Sample turn-around can be
50% faster, or more, than with alternative columns.
Applications in this 8-page publication include polyaro-
matic hydrocarbons, carbamates, phenoxyacid her-
bicides, explosives, and carbonyls. Analytical refer-
ence materials and solid phase extraction sample
clean-up products also are listed.
