Orion 1800 Series
1800 Series 33% monoethylamine
E3057-6L: 6x1L,with 4' diffusion tubing, is the our ethylamine, 33%, that is used to adjust the pH of incoming samples prior to analysis by the Thermo Orion Models 1800 Series. Raw material for this product is 70-71% monoethylamine upon which most MSDS data is founded on.
Analysis is provided for monoethylamine wt%, Color, APHA, ammonia wt%, diethylamine wt%, N-ethylidene-ethylamine wt%, and total organic impurities wt% as measured by GC on a 100% organic basis.
It is then diluted to 33%, an exothermic process, as outlined in E3057-45.
Once diluted the flash point hazard is greatly reduced: from -17 deg C to ~22 deg C.

The good? You may already be using it, and are where you need to be for sensitivity.
Not to mention the fact that this configuration has been a good old work-horse.

It is sold packaged in 6x1L case only, shipped in a non-breakable leakproof bottle, along with 6 diffusion tubing/o-ring kits.
