Auto Dilution of Standard and Sample Solutions Using the SIL-30AC Autosampler

When conducting quantitative analysis by HPLC, dilution of standard solutions and sample solutions is typically performed manually. Not only does this operation require some degree of experience and knowledge, the time and effort associated with these tasks are certainly not insignificant. With recent advances in instrumentation technology, there is considerable expectation that labor savings through automation will enable improved throughput. Delivering on this expectation by automating these dilution-related tasks should have a very positive impact on productivity.
The Nexera^? SIL-30AC autosampler system incorporates such pretreatment functionality as a standard feature, allowing dilution and reagent addition to be fully automated.
Here, we introduce an example of analysis of caffeine in beverages using the pretreatment feature of the SIL-30AC.
