TPW3 gravimetric control reports the exact reagent volume for each dispense. This value is retained in the compliant database to determine dilution factors
Since each step is controlled by accurately defined parameters there is no technique dependency. This includes the conditions controlling extractions and dilutions
Timing between the method steps, including HPLC injection, is identical for every sample resulting in a uniform sample history
Methods may also be overlapped so that the output tube of one method may be the starting point of another method
The TPW3 includes an interface to Water’s Empower® IITM. The TPW3 can also be connected with an on-line generic HPLC and UV spectrophotometer
The TPW3 is designed to allow multiple dilutions and HPLC injections so that different concentrations from the same extraction can be analyzed
Design of experiments, or DOE, is facilitated by the ability to designate analytical parameters as variables. This is a powerful tool that realizes the full potential of automated method development
