Sample preparation/Extraction
- Better extractions
- In less time
- Using less solvent

Solvent extractions that normally require labor-intensive steps
are automated or performed in minutes, with reduced solvent
consumption and reduced sample handling using Accelerated Solvent
Extraction (ASE®) or AutoTrace® systems.
ASE systems use a patented technique for the extraction of solid
and semisolid samples using common solvents at elevated temperature
and pressure. The ASE 150 and 350 systems feature pH-hardened
pathways with Dionium™ components to support extraction
of acidic or alkaline matrices, and combine pretreatment, solvent
extraction, and cleanup into one step. Dionium is zirconium that
has undergone a proprietary hardening process that makes it inert
to chemical attack by acids and bases at elevated temperatures.
ASE systems are dramatically faster than Soxhlet, sonication,
and other extraction methods, and require significantly less
solvent and labor. ASE methods are accepted and established in the
environmental, pharmaceutical, foods, polymers and consumer product
industries. ASE method are accepted and used by government agencies
worldwide.

The AutoTrace 280 instrument performs automated solid-phase
extractions (SPE) of large volume liquid sample matrices. The
instrument automates the standard SPE steps of condition, load,
rinse, and elute to reduce sample handling and improve
productivity. AutoTrace systems are available in cartridge or disk
formats, and can be used for numerous US EPA methods requiring
extraction prior to analysis.

Solid Phase Extraction
Solid-phase extraction
(SPE) is a technique for liquid-liquid extraction that is used
to remove certain compounds from a mixture of impurities based on
their physical and chemical properties. Analytical laboratories use
SPE to concentrate and purify samples for analysis. SPE can be used
to isolate analytes of interest from a wide variety of matrices,
including urine, blood, beverage, and water samples. SPE
requirements vary depending on the amount of sample required. SPE
systems can be separated into large or small volume techniques.
Large volume techniques generally use 100 mL or more of liquid
sample.
The AutoTrace SPE instruments reduce labor and solvent
consumption by up to 90% when compared to traditional liquid
extraction techniques. AutoTrace automates the SPE process to
provide high sample throughput combined with reliable analytical
results.
LC Sample Preparation Solutions
In preparative
chromatography the goal is to isolate a large quantity of
organic target molecules during each run. Dionex demonstrates how
the deficiency of a limited mass loading capacity can be overcome
by using adaptable and sophisticated sample injection
procedures.
