Robotic Sample Processor

Table 4.15 fists the many possibilities for solid sampling for GC analysis. In general, sample preparation should be considered in close conjunction with injection. Robotic sample processors have been introduced for automatic preparation, solvent extraction and injection of samples for GC and GC-MS analyses. Usually, facilities are included for solvent, reagent, and standard additions and for derivatisation of samples.

If automation is viable, the type of automation chosen (e.g., robot, sample processor, or autosampler) will depend upon the expertise and availability within a given laboratory as well as consideration of the items above. 

Sample preparation is often one of the rate-limiting factors of sample throughput for many methods. Furthermore, it is a critical factor for determining the accuracy and precision of analytical results. The final aim of any sample preparation scheme must be to isolate and purify the compound of interest and present it in a form that is compatible with the analytical instrument. The task facing analytical chemists is to select and use the many diverse systems available, such as robots, sample processors, and autosamplers, to achieve that goal in a timely and cost-effective manner. 

Batch size The number of samples per batch should be considered in relation to the analytical objectives. A large number of batches containing many samples would benefit most from automated sample preparation and analysis as it allows the widest choice for an automated system robotics, sample processors, or column-switching systems. 

Profile Founded in 1980, the company is involved in the development and manufacture of robotic liquid-handling systems, automated sample processors,... 

Some automatic sample processors are also analytical instruments such as LC, flow injection analyzers, or autoanalyzers. There is a trend, wherever possible, to merge the sample preparation technique with the instrumental analysis. This allows greater efficiency and productivity. In addition, there are robots and sample processors that can be used to automate sample preparation. 

The quantification of the acids such as quinolinic and nicotinic acids proceeds into two stages. The first stage consists of extraction and concentration of the compounds from biomaterials. This procedure is so complicated that the reproducibility of the recovery of the target compound is poor in some cases. The progress of computer technology will make it possible to use automated sample pretreatment systems (e.g auto injector with pretreatment function for HPLC and/or advanced automated sample processor) or by a laboratory robot (e.g., a robotic system for HPLC or an automatic preparation system for HPLC) with high reproducibility.
