AGROCHEMICAL AND FOOD
ISOLUTE Multimode SPE Columns for Acrylamide Clean-up
Determination of acrylamide in cooked foodstuffs such as fried potato products can be problematic due to the
highly polar, water soluble nature of the analyte, and the complexity of the sample matrix. ISOLUTE Multimode
SPE columns provide an extremely effective clean-up of aqueous food extracts, allowing acrylamide determination
by LC-MS.
See Application Note IST1076 Extraction of Acrylamide from cooked Foods.

ISOLUTE ENV+ SPE Columns for Extraction of Highly Polar Compounds
ISOLUTE ENV+ is an extremely retentive SPE sorbent used for
extraction of highly polar pesticides and herbicides from aqueous
samples. Unlike other polymeric SPE sorbents, it is able
to retain highly water soluble compounds such as acrylamide
from aqueous food extracts.
Ordering information for ISOLUTE ENV+ SPE columns can be
found on page 34.
See Application Note IST1082 Extraction and Clean-up of
Acrylamide from Foodstuffs.
ISOLUTE Filtration Columns and Depth
Filter Reservoirs
When extracting samples containing particulate material, is often necessary to pre-filter the sample prior to
SPE. This prevents blocking the SPE column. ISOLUTE Filtration Columns contain two 20 µm polyethylene
frits, and can be connected directly above the extraction column for direct sample loading and in-line removal
of suspended solids.
For samples containing higher levels of suspended solids, ISOLUTE Depth Filter Reservoirs should be used.
Ordering information for ISOLUTE Filtration Columns can be found on page 98.
Ordering information for ISOLUTE Depth Filter Reservoirs can be found on page 96.
