Whether your laboratory uses Liquid Nitrogen or your desire is to be LN2 free, Entech has the most advanced and accurate solutions in the industry. For TO15 and the new TO15A canister methods, Entech is now introducing an even faster LN2 based solution, our 7200A, that nearly doubles the sample throughput of our previous LN2 based technology, while still offering all the superior water management and accuracy that our customers have come to expect. Rather than taking 45-50 minutes injection to injection, the 7200A does this in typically under 25 minutes, thanks to our new EFIT – Extremely Fast Injection Technology.
With EFIT, the sample is deposited on the column in less than 1 second, producing peak widths of just 1.7 – 2 seconds to allow separation with shorter and narrower columns with only 0.5 um film thicknesses. The 7200A with EFIT creates a whole new standard of productivity with the complete suite of TO-15 compounds eluting in under 10 minutes!
Doubling your throughput is like someone giving you a free GCMS, as well as another free preconcentrator, since one system can generate the data of 2 systems. Would you spend another $2-3 in LN2 to allow you to run another sample without the space or cost of another GCMS? Whether you are a contract lab or an agency needing to improve efficiency, faster throughput simply makes good sense. As costs lower, your ability to compete dramatically increases, allowing you to stay ahead of the curve.
Available on GSA.
Extremely Fast Injection Technology (EFIT)
Extremely Fast Injection Technology (EFIT) that reduces bandwidth to 1 second or less on column
Much shorter run times and cycle times = Higher Productivity
Cycle times injection to injection as short at 20-25 minutes for a 250mL sample size.
Complete elution of TO15 compounds in under 10 minutes, with column bakeout done in just 2-3 additional minutes
Reduced LN2 consumption compared to prior Entech preconcentrators (7100A, 7200)
Lower carryover by optimizing Silonite coated flowpath temperatures and M3 bakeout timing
Superior water management reduces impact on GCMS relative to prior art
Less column bleed resulting in better baselines and fewer source cleanings
Advanced software that improves the user experience
Supports up to three 16 position autosamplers to allow up to 40 samples or canister blank certs to run overnight, or 48 to run over the weekend
Supports 7650-M for 1L soil gas canister analysis, and 6 minute screening from injection to injection (10 samples per hour!)
Accu-Sample Technology combines digital valve control with direct volume measurement rather than indirect time integrated flow measurements to allow small volume accuracy to 10cc over a wider pressure range while allowing air and non-air matrices to to be analyzed accurately.
