HPLC System Controller

The CBM-20A/CBM-20Alite is the world's first Web-based HPLC system controller. Equipped with a data buffering function, the CBM-20A/CBM-20Alite acts as an interface for connecting LC workstations, network-client computers, and analytical instruments via Ethernet. An easy-to-use Web interface enables users to set-up, control and monitor their HPLC remotely. This centralized management ensures efficiency, offers added security with multi-level user access options, provides a flexible analytical environment, and helps to conserve valuable bench space.
Up to eight modules can be connected. Adding up to two A/D conversion boards makes it possible to accept an analog signal from non-Shimadzu detectors.
The space-saving card-type CBM-20Alite is installed inside an LC-20A series pump or autosampler, and can control up to five modules, including the one in which it is installed.

Flexible Installation Environment
Connected via LAN cables to the laboratory's Ethernet, computers controlling the analytical instruments can be accessed remotely. The CBM's data buffering function (available only with LCsolution software) protects important analytical data from unexpected communications errors.
Integrated Web-Control Functions
In addition to an Ethernet connection, the CBM-20A/CBM-20Alite is equipped with Web-control functions. These allow system control, monitoring, and maintenance information to be accessed from Internet Explorer without installing special software. Now, from a remote location, like your home or office, you can:
  • Schedule maintenance for consumable parts
  • Perform baseline check or system equilibration
  • Monitor current analysis
  • Save time by reducing visits to the laboratory to check on hardware
Auto-Purge with a Modular HPLC System
Equipped with auto-purge, user intervention is not required to open or close the drain valve. All pumps and autosamplers are purged on command or automatically. When combined with the system startup and baseline-check functions, fully automated analysis is achieved with a modular HPLC system.
Monitor Device Status at a Glance
With this function, the operating status of networked devices can be checked at a glance. You can monitor:
  • System activity
  • Status of individual units
  • Existence of errors
  • Device maintenance information
A memo function allows users to post messages regarding the status of components or to allow users sharing the system to leave messages for each other.
