Evaluation of bactericidal efficacy of sulfur nanoparticles (SNPs) against multidrug resistant isolates of Escherichia coli and Klebsiella pneumoniae

Analysis of Extract Drying Criteria for Oil & Grease Method 1664A/B

Sample preparation is a key step in the analysis process

Parameters for evaporation and their impact on analysis have been discussed

Improvements in matching the sample to the evaporation device characteristics can help reduce variability and improve recovery

Examples for choosing a system based on sample volume, types of analytes, sample load, and initial investment considerations

Automated sample preparation reduces the costs per sample and minimizes sample handling errors. Usually expensive and highly specialized pipetting robots are used. However, most of these systems are not designed with a direct interface for LC-MS applications. In addition common pipetting systems are not optimized for smaller scale sample series. Here we present a new tool for liquid handling of whole blood samples and direct sample injection.
