High Throughput and Rapid Response Chromatography Solutions

Laboratories that face large numbers of samples or require results fast, can find the analysis cycle times of conventional air blown oven gas chromatographs (GC) to be a limiting factor. Other manufacturers have attempted to address this problem by simply implementing larger powered heaters and forced cooling systems. Ellutia considers  this approach to be inefficient as it increases the amount of energy required per sample. Many Users also complain about the waste heat emitted, noise produced and bench space occupied by the cumbersome dimensions of most conventional GCs. Ellutia believes the solutions to these problems lies with the elimination of the need to heat a column oven. With the use of direct resistive heating of the column, the smallest mass possible is heated and cooled rather than an entire oven. This can allow heating rates of up to 1200°C per minute and a cool-down time from 400°C to 40°C in under 60 seconds. Ellutia can offer this technology in either a standalone GC system or an upgrade for customers’ existing GCs. The 300 Series GC was designed without a column oven, instead directly heating commercially available metal columns. Removing many components that would be required for a conventional column oven design, allows the 300 Series GC to be uniquely compact, with a foot print of just 37 cm x 32 cm and near silent operation. The system is ideally suited for high sample throughput and can analyse nearly 500 samples in 24 hours. EZ Flash is an accessory allowing users to experience the awe inspiring benefits of low mass resistive heating chromatography with their existing GCs. EZ Flash interfaces with the existing injector and detector of most commercially available GCs and directly heats a metal sheath containing a fused silica column.

Main application areas for these types of instrument include: Where a rapid result is required, i.e. process or reaction monitoring, a  the reduced cycle times allow more frequent information about the progress to be recorded.

Where large numbers of  samples are required for environmental or safety reasons, many have little or no compounds of interest present. Rapid GC systems are used to screen out positives for further detailed analysis.

The low power consumption and compact size of directly heated systems lends themselves to portable applications.
