Solution preparation is the first operation that has to be performed for the vast majority of samples that are submitted to an analytical laboratory. Accurate solution preparation and documentation is, therefore, the foundation for the overall integrity of any analytical laboratory. The Design Scientific SoluPrep System is designed specifically for this purpose.
The most common way of obtaining high quantitative accuracy in HPLC, GC, AA, Mass Spectrometry and other techniques is to spike an unknown concentration of a sample with a known amount of another substance—commonly known as an internal standard. After the sample is analyzed, the response to the unknown concentration is compared to the internal standard and an accurate measurement of the concentration of the substance of interest is obtained.
The SoluPrep Solution Preparation System saves labor while increasing accuracy when preparing solutions having an internal standard. The SoluPrep does this in five labor saving steps:
- Operator enters the sample number and his/her initials.
- A sample bottle is placed on the balance and the computer records the weight.
- Operator is prompted to add the appropriate amount of solute to the bottle.
- The computer calculates the exact amount of solvent required. The solvent, with the internal standard dissolved, is added to the sample to obtain a dilution with a typical accuracy of 0.02%.
- The completed sample is removed and the printed sample label is affixed to the bottle
