Agilent Polystyrene EasiCal Standards
The EasiCal system for organic solvents consists of two different combs, each with ten detachable spatulas supporting a mixture of five polymer standards. The thin film of polymer (approximately 5 mg) on the tip of the PTFE spatulas rapidly dissolves when immersed in eluent to provide two GPC/SEC calibration solutions. A single pack provides ten spatulas of each type, with MWs selected to provide equidistant calibration points for greater accuracy.
- Easy three step process with no fuss
- Cost effective format saves money
- Only two injections for improved productivity
The EasiCal system consists of two different combs, each with 10 detachable spatulas supporting a mixture of 5 polymer standards.
