Preparative Purification Liquid Chromatograph
The LH-40 Liquid Handler, Combination of Autosampler and Fraction Collector
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.
Multi-Liquid Handler Kit*1
Up to six LH-40 liquid handlers can be connected, making it easy to inject the sample from all LH-40. *1 Up to one LH-40 when FRC-40 fraction collectors are connected.

Example of Scaling Up from Analytical to Semi Preparative Work
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.

DGU-403 : 3 flow lines, DGU-405 : 5 flow lines - The maximum operating flow rate per flow line is 10 mL/min.
- Designed for use in analytical and preparative fractionation, this unit is used only when retention time reproducibility needs to be improved during analysis.
* When connecting to an LC-20AP, a connection kit must be obtained separately.
* LC-20AR connection kit is required when the operating flow rate is more than 10 mL/min.
Helium Degassing Unit
