This technique offers: l Separation of closely related compounds. l High sensitivity and specificity. Sample preparation involves pigment extraction followed by injection into the HPLC system. ...
While effective, this approach suffers from lengthy sample preparation times and co-elution. Combining HILIC-FD detection with RapiFluor MS labeling and MS identification overcomes these limitations, providing swifter sample preparation and enhanced sensitivity. ...
To address this challenge, two general strategies are available: the addition of separation methods such as 2D-LC and/or ion mobility to remove interfering peptides and improve separation efficiency, or focusing on sample preparation by enriching HCPs through affinity purification or molecular weight cut-off (MWCO) ultrafiltration. ...
The low odor thresholds of many of these compounds, some below 10 parts-per-trillion, necessitate extremely sensitive sample preparation and analytical techniques for their determination. This application note will demonstrate a new purge and trap method for analyzing drinking water samples for these mold odor compounds at the ...
In the dynamic headspace method analytes are swept and concentrated on a sorbent trap that greatly increases compound sensitivity and decreases sample preparation time. Read the full article Click ...
SPME was used to extract an aquatic sample for analysis of organophosphate insecticides by gas chromatography/mass spectrometry (GC/MS). An SPME fiber coated with 8.5um of polyacryate yielded detection limits ranging from 0.10 to 0.56ug/L. SPME is a quick and highly sensitive sample preparation technique that eliminates the use ...
