* When attaching three or more analytical columns or two preparative columns to the column hub, the optional "Column Bracket" is needed.

** If two preparative columns are attached using the column holder SLIM, the optional column clamp ASSY (P/N: 228-17701-94) is required.

Column Holder

For Multiple Detection Triggers

A/D Conversion Board Kit

This is required for preparative work using multiple detector triggers. Expand the hardware to suit the number of detection trigger channels required.

 

Degassing Units

DGU-403 / DGU-405


DGU-403
  • A low-capacity degassing unit that uses a special fluororesin membrane.
    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

DGU-10B


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.
  • This unit is switched ON/OFF from the solvent delivery unit or system controller.
 

High-Pressure Flow-Line Selection Valves

FCV-20AH2 / FCV-12AH

  • The valve position is controlled by event signal input.
  • Valve type: 2-position/6-port rotary valve (recycle valve : 2-position/3-port valve)
  • 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.

High-Pressure Flow-Line Selection Valves

Low-Pressure Gradient Unit

FCV-200AL


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

FCV-11AL / FCV-11ALS / FCV-230AL

  • 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.
