Minimizing Carry-over for High Throughput Analysis
1FHNW Fachhochschule Nordwestschweiz, Hochschule für Life Sciences Gründenstrasse 40 CH-4132 Muttenz; 2CTC Analytics AG Industriestrasse 20 CH-4222 Zwingen; Switzerland

Minimal carry-over is a prerequisite for high throughput analysis. However, minimized carry-over and cycle time are competing and a careful optimization is mandatory. In this study the influence of wash conditions on carry-over of various compounds was investigated. A strategy to minimize carry-over was developed. The influences of different wash tasks were investigated. Finally the contribution of different system components such as injector valve or column was studied.
A Comparison of ITEX Dynamic Headspace–GC/MS to other Enrichment Techniques for Analysis of Flavoring Compounds
1Aspen Research Corporation, Maple Grove, MN; 2CTC Analytics, Zwingen, Switzerland

Enrichment techniques are commonly used for the analysis of flavoring compounds in different matrices with GC/MS. Analysis of flavoring compounds is done by purge & trap, SPME or headspace, depending on requirements for sensitivity. The In-Tube Ex¬traction (ITEX) Dynamic Headspace uses a micro trap filled with an adsorbent material to efficiently extract the compounds. Here we evaluate if the ITEX can be used to effectively analyze for these compounds and reduce the analyst’s time involved.
High Performance Comprehensive Two-Dimensional Gas Chromatography Coupled with a High Resolution Multi-Reflecting TOFMS for Confident Non-Target Analyte Identification

Douglas Scientific

With greater portability than real-time PCR instrumentation, the AmpliFire produces rapid and accurate results in the field or in the lab without cumbersome equipment or reagents. In a recent study, the AmpliFire® accurately detected the presence of Salmonella enterica using both purified genomic DNA and a crude sample preparation method, making it a powerful tool for point of use applications.
Automated Sample Preparation of 25-OH-Vitamin D3/D2 from Serum with the AC Extraction Plate and the Tecan Freedom EVO® for the quantification by LC-MS/MS
Tecan Group Ltd.

There is an increasing demand for the determination of Vitamin D status which is based on the quantification of the two metabolites 25-OH-Vitamin D3/D2. Numerous laboratories have moved from the use of immunoassay methods to liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) because of its specificity combined with high sensitivity. Moreover LC-MS/MS offers the potential for multianalyte determination which is required for Vitamin D status determination.
Sample preparation with the AC Extraction Plate: extraction of urinary THC metabolites for LC-MSMS quantification
Tecan Group Ltd.

Optimization of Instrument Settings and Measurement Parameters for Kinetic Fluorometric and Luminometric Assays
Thermo Fisher Scientific

When fluorometric and luminometric assays are performed in microplate format, a high number of samples can be analyzed at a time. The speed of the reaction kinetics of the assay determines the requirements for the detection instrument and measurement parameters for achieving the best possible performance of the assay.
Turbidometric Growth Curve Measurements and Liquid Evaporation Studies with a Microplate Photometer
Thermo Fisher Scientific

The turbidity of a liquid sample is traditionally measured either with a nephelometer or a photometer. The measure of turbidity (also called optical density, OD) refers to the scattering of light from the particles of the measured sample. When measuring turbidity of a bacterial culture, the amount of scattered light is directly proportional to the number of bacterial cells in the sample.
