The LH-40 Liquid Handler, Combination of Autosampler and Fraction Collector

LH-40 Liquid Handler

Options

Syringe Kit 20 mL

This kit enables large-capacity injections of 2 mL or more at one time. The maximum injection volume is 20 mL.

Washing Pump

This reduces the washing time for the injection needle, increasing throughput while reducing carryover.

 

Analysis Kit

The recovered fraction can be reanalyzed to check the purity.

Liquid Surface Detection Needle

This detects the liquid surface level, and automatically determines whether there is any sample present. As a result, only the remaining volume is injected, which prevents the injection of air into columns. Additionally, if no sample is present, the system can proceed to the next sample, reducing needless errors and lost labor.

Example of Scaling Up from Analytical to Semi Preparative Work

Example of Scaling Up for Parabens

This is an example of scaling up in which seven types of parabens are targeted using a 150 mm long column with a particle size of 5 μm.
The gradient elution conditions investigated at the analytical scale are transitioned to the semi-preparative scale. A comparable chromatogram is obtained at both scales.

Column: Shim-pack Scepter C18-120 (4.6 mm x 150 mm,5 μm)
Column: Shim-pack Scepter C18-120 (20 mm x 150 mm,5 μm)
