Analysis of Protein Hydrolysate Amino Acids using OPA Post-column Derivatization by Quaternary Low Pressure Gradient System

The LC-4000 Series column ovens have been designed to provide excellent utility for a wide range of different user requirements.For simple requirements the stackable CO-4061 can be used with column lengths up to 200mm (or up to 300mm with an optional extension). For RHPLC and UHPLC the CO-4062 has capacity for up to six 150 mm length columns, with optional one or two internally mounted automatic switching valves for 2 or 6 column selection. For GPC and larger preparative columns, select either of the two high-capacity CO- 4060 or CO-4065 ovens. The CO-4060 can accommodate columns with lengths up to 300mm or larger ID preparative columns. The CO-4065 can accommodate up to 10 columns with lengths up to 300mm and a pair of column selection valves is included as standard. All column ovens have built- in electronic cooling for controlling column temperature at sub-ambient temperatures. The CO-4062 and CO-4061 block-heater type ovens can be fitted with an optional micro-volume pre-heating unit for pre- heating the mobile phase before the column to improve resolution and peak shape. The RO-4068 reaction oven is used for high temperature post-column sample processing with capacity for columns and reaction coils.

The LC-4000 Series autosamplers provide a range of options to suit any sample injection requirements, from the AS-4050 entry-level model, to the AS-4250 UHPLC model or the AS-4058 preparative scale autosampler. All LC-4000 series autosamplers share the same simple maintenance features, with consumable parts such as injection ports, rotor seals, and loops accessible from the front panel for easy replacement.

The LC-4000 series HPLC pumps include expansion bays that allow a simple pump module to be transformed into a powerful solvent delivery system.Accessory modules can be installed in the LC-4000 series pump for use with virtually any solvent delivery requirement.
