Description

Several analysis tools are available for cell-based research e.g. facilities to carry out polymerase chain reactions (PCR). The qTower³ G touch qPCR machine is a 96-well format and currently uses one SYBR Green module, however, can be equipped with up to six for multiplexing capabilities. One main function of this system will be to evaluate stress parameters on microbial communities collected from Arctic snow and ice samples.

Instruments

Real-Time PCR Cycler
Total Organic Carbon (TOC) analysis is a well-defined and commonly used methodology that measures the carbon content of dissolved and particulate organic matter present in water. Many water utilities monitor TOC to determine raw water quality or to evaluate the effectiveness of processes designed to remove organic carbon. Some wastewater utilities also employ TOC analysis to monitor the efficiency of the treatment process. In addition to these uses for TOC monitoring, measuring changes in TOC concentrations can be an effective "surrogate" for detecting contamination from organic compounds (e.g. petrochemicals, solvents, pesticides). Thus, while TOC analysis does not give specific information about the nature of the threat, identifying changes in TOC can be a good indicator of potential threats to a system.
