Applications
Column durability against water elution
Organic acids
Ultra-low pressure column with particle size of 3mm ODS D-210SLP series
Low column pressure was realized by particle size of 3 μm
By eliminating minute particles of packing materials and improving the filling method, the lowest level column pressure was realized.
They allow analysis using an ultra-low pressure while ensuring high performance of the filler with a particle size of 3 μm. As shown in Figure-1, the column pressure is extremely low not only for acetonitrile but also for methanol with which the column pressure becomes higher depending on the mixing ratio with water, realizing good separation in a short time by a large number of theoretical plate.
Column pressure
Durability
As the mobile phase, a methanol/water gradient phase was selected for its huge impact on the column pressure depending on the mixing ratio. As a result of column durability test, there was no major change in the number of theoretical plate after injecting 400 times (Figure-2).
