On-line automation of sample preparation can not only guarantee control over the way the sample is prepared through the whole batch but can also significantly optimise time and analyst efforts.
Fully automated methods for on-line sample preparation of three product samples (tablet, lozenge and liquid) were developed. The LC system offered very good repeatability (0.1%-0.7%).
Replicate on-line automated preparations (n=9) of the three investigated product sample proved very reproducible (RSD% 0.7%-1%) and provided significant time savings.
