Introducing Chrom-Prep..... a new disposable minichromatography column for analytical sample prep-
arations. The Chrom-Prep cartridge fits snugly into a handy lightweight holder that mounts easily on your syringe-needle. (You’ll need a removable needle, 3A" in length.) It works with syringes from volumes of 10 µ . to 10 ml.
Chrom-Prep is easy to use! For clean-up procedures, simply fill the syringe and pump the eluant
easily through the cartridge... directly into your HPLC loop-valve. For enrichment procedures in trace analysis, fill the syringe through the cartridge to preferentially adsorb the ana-
lyte. Refill the syringe with an
appropriate solvent and
elute from the cartridge direct into your HPLC or other analytical instrument. Chrom-Prep is efficient! The disposable cartridge is packed with Hamilton's new
polymeric reverse phase resin, or optional anion/ cation exchange resin, depending upon your application. After use, just toss away the used cartridge and
NOW PURE AND SIMPLE
