In the main, I'd like to thank Scientist Sarah for raising such question; it's really a good question that reflects how care you're even when choosing your research area. It's very important to scan the market you're interested in so that you can make and take a rational decision. Accordingly, I do advise you, Sara, to check market research reports. Frankly speaking, I don't have an access to such reports in the mean time; however, I do know how important they're. Sadly, these reports are very expensive to buy for early researchers like me; nonetheless they are so important in shaping the mindset of an early stage researcher and expert researchers, too. You can contact market research firms, e.g., http://www.bccresearch.com/
I wonder if Gammy can provide you with such industry report. Honestly, I'm not quite sure about this information; however, I'd appreciate it if Scientist Ali can elaborate more on his gentle response. As far as I know, Gammy is a manufacturer of lab instruments, so do they offer market research reports, too?
I'll appreciate your kind feedback, Scientist Ali.
