Sample throughput can be a concern for many analytical laboratories, especially those dealing with a large number of samples, or with critical samples that require fast turnaround. Related to this is the desire to reduce the cost per sample, which is common to many laboratories.
All these issues can be addressed by using HiSorb™ high‑capacity sorptive extraction to eliminate time-consuming and costly manual sample preparation. The technique uses robust, sensitive and selective PDMS probes, which are compatible with immersive or headspace sampling of liquids and solids. Importantly, when implemented on Markes’ Centri® sample automation and preconcentration platform (Figure 1), HiSorb offers higher sample throughput than methods such as SPME, thanks to full automation of the entire workflow using gold-standard robotics.
