PRODUCTS FOR ENVIRONMENTAL APPLICATIONS<br />
Extract purity is essential for reliable analyte quantification at trace levels for environmental applications. These<br />
very demanding requirements are met by ISOLUTE SPE column components (sorbents, columns and frits) and<br />
VacMaster Sample Processing Manifolds. All column components are cleaned to a high standard and quality<br />
controlled for purity using both GC and LC techniques. VacMaster Sample Processing Stations, constructed from<br />
inert materials, avoiding sample interference, also provides productivity enhancements for the environmental<br />
laboratory.<br />
Biotage’s range of products including analyte specific columns and methodologies, and innovative accessories<br />
designed specifically to solve environmental sample handling problems are highlighted in this section.<br />
ISOLUTE ENV+ SPE columns<br />
Efficiently extract polar analytes from water samples using ISOLUTE ENV+ SPE<br />
columns. This hyper-crosslinked polystyrene-divinylbenzene polymer based sorbent<br />
has a wettable, hydroxyl modified surface with an extremely high area (>1000 m 2 /g).<br />
The sorbent is optimized for loading large volume samples, and high analyte recoveries<br />
are achieved when loading at fast flow rates of 60 mL/min.<br />

Please request Chemistry Data Sheet TN109 for method development guidelines using ISOLUTE ENV+ SPE<br />
columns. Ordering information for ISOLUTE ENV+ SPE columns can be found on page 34.<br />
EVOLUTE SPE columns<br />
NEW EVOLUTE polymer based SPE products are now available in formats optimised for extraction of environmental<br />
samples.<br />
EVOLUTE ABN is designed to efficiently extract multi analyte suites from aqueous samples. Request application<br />
note AN701 for further details.<br />
EVOLUTE CX is designed to provide very clean extracts of basic compounds in aqueous samples, and may also<br />
be used for class fractionation applications. See www.biotage.com for the latest applications.<br />
