High Performance Liquid Chromatography has indeed brought a sea-change in the way complex samples are analysed and tested. HPLC instruments have found their way in various industries where these are used for quality assurance, testing and much more. There are several components which make up an HPLC instrument and out of these autosampler is one of the most important. Autosampler helps you introduce samples into the inlet. You might argue that manual insertion is possible than why the need for an autosampler? Well, it helps in time-optimization and reproducibility as well. Countries such as the United Kingdom, United States & Italy have been at the forefront when it comes to designing & developing the autosampler technology. While buying autosamplers for your HPCL instrument, you need to keep in mind some points which are briefly discussed as under-
Begin by asking how many samples actually you need in your laboratory on a periodic basis. If you analyze thousands of samples, then investing in autosampler is a great idea! On the other hand, if you deal with limited samples, a manual injector does the needful for you at a lesser price. However, if you prefer accuracy than the cost-factor, autosamplers offer amazing results. Once you have dealt with this point, its now the time to ask what exactly are the size of samples that you need to analyze. It is a proven fact that autosamplers are far more efficient than human beings. Investing in an autosampler is a good idea even if you have to deal with low-volume samples in your laboratory.
After having analyzed these points, you need to know how fast your instruments cycle time and the sample loading speed are. It is worth considering these points in case speed is important to you. It is very much crucial to choose the right supplier when you are buying an HPLC autosampler. Find out the kind of services, support the supplier offers including warranty. Most importantly, you also need to find out the cost of buying the autosampler and maintaining it. Go for a supplier who offers complete technical support to you all round the year, whenever the need arises. It is better to invest a substantial time in choosing the right supplier because the quality of autosampler and the kind of support you get matters a lot.
Considering factors such as the ones described above will help you decide whether investing in an autosampler is worthwhile. In nutshell, autosamplers are not meant for every lab use. Many researches still rely on manual insertion because of the cost-factor linked with autosampler. However, if speed and accuracy are your priority, then autosampler can help achieve your target objectives in quick time.
