Sample Preparation with the ESSLAB Gravimetric Dosing System (GDS)
The New Standard in Automated Preparation of Reference Materials
"Your analytical data is only as good as the standards you use"
With Cubis® individual for Standard Preparation your analytical testing results will reach a new level of significance and validity never realised before.
Imagine the following future scenario: You need to prepare reference material (RM) for your highly sensitive analytical method. You simply start the application ‘Standard Preparation’ over your lab balance display. You select the compound and solvent from the Apps library. Immediately, your balance shows you a precise workflow following your Standard Operating Procedure (SOP). The step by step guide confirms the target weight to be prepared.
Already corrected for purity of compound. The App shows you how much of the reference compound you need to weigh in. Even if realizing exact target weighing to the 5th place is rarely achievable: No need for corrections or worry. The App will simply recalculate the volume of solvent that needs to be added to still meet the target concentration. The App automatically makes corrections for density and temperature of the solvent.
The exact volume of solvent you need to add to your compound will now be automatically aspirated, and may easily be dispensed by you. With the highest possible precision. You will be 100% sure that the reference standard exactly meets your target concentrations. realise your target concentration with accuracy and precision independent of, and unaffected by, analyst technique. This time, and every time you prepare your standard in the future.
Forget about cumbersome, time-consuming, and error-prone manual preparation
of questionable reference standards by using volumetric glassware. Sartorius sets new standards in the future preparation of RM for your highly sensitive analytical testing: With Cubis® individual and Q-App for automated Standard Preparation.
In analytical chemistry the use of RM‘s and standards is the means by which we may have confidence that the measured values we realise are accurate. The method by which we determine the measured value, our SOP, should ensure that the value is accurate and precise.
In collaboration with ESSLAB, Sartorius managed to combine our high-accuracy weighing with Hamilton high-accuracy liquid handling, producing an innovative system for fully automated gravimetric standard preparation. Perform your standard preparation with 100% confidence in accuracy, consistency, traceability, in compliance with international regulations.
