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.

FRC-40, Highly Flexible Fraction Collector
Sample Racks
A variety of containers can be placed including MTPs, vials, and various types of test tubes. Six colors are available, so a separate color can be apportioned to each user in order to avoid confusing samples.
Multi Fraction Collector Kit
Up to six FRC-40 fraction collectors (up to five LH-40 liquid handlers) can be connected, making it easy to increase the number of fractions.
Compact Design for Small-Volume Samples
FRC-10A
For smaller scale collection, or specialized applications that require enclosure and cooling, the FRC-10A is a compact fraction collector that provides time and signal based triggering. A variety of programmable fractionation functions enable target components to be collected with high purity and high recovery.

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.
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）

Column Hub
Column Holder
Column Holder SLIM
Preparative columns with an I.D. of 20 mm to 50 mm as well as manual switching valves can be attached. The valves can be used for column switching.

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.
* LC-20AR connection kit is required when the operating flow rate is more than 10 mL/min.
Helium Degassing Unit
DGU-10B
- Eliminates air bubbles, baseline undulation, drifting, etc. by purging dissolved air from mobile phases.
- The DGU-10B can be used to degas up to four mobile phase solutions with helium gas.

- Maximum operating pressure: 34.3 MPa
- Operating pH range: pH 1 to 10
- Operating temperature range: 4 to 35°C
- Storing the FCV-12AH in the Option Box helps reduce the volume of preparative piping, including the recycling flow lines.
Low-Pressure Gradient Unit
FCV-200AL
- This low-pressure gradient unit is for the LC-20AP large-volume solvent delivery pump.
- A gradient can be produced with a single pump, enabling gradient preparative work at low cost.
- A single unit is capable of providing up to a four-liquid gradient as well as solvent switching, reducing the work involved in mobile phase investigations during method development.
Reservoir Selection Valves

- Capable of switching solvents using solenoid valves.
- The FCV-11AL/FCV-11ALS provide switching between two solvents. The FCV-11AL can supply up to three solvent delivery units, whereas the FCV-11ALS is used for one unit. It can be controlled from the LC-20AP/20AR front panel directly or through a system controller CBM-20A/20Alite and workstation software.
- The FCV-230AL provides switching between two solvents (optionally four solvents). It can be controlled from the LC-20AP/20AR front panel directly or through a system controller CBM-20A/20Alite and workstation software.
