Ian, we measure these parameters on forages for 20 years. I have a cheap solution for you. If you want, contact me ditectly at [email protected] Pierre | ||

Well, according to the post of Don, it looks like you need a machine that can go up to 2500 nm, not all machines can do that. My alphabet soup is only interesting if you are in a large company where the (immediate) flow of information is important, probably not a university. Start by looking if you can find more existing papers about your subject. Look if you need certain wavelengths and what other people have done as sample preparation: grinding, drying... The Brimrose machine suggested is certainly a good bid, but last time I worked with one it only went up to 2400 nm. If you want to go so high wavelengths you may want to avoid using fiber optics because the silica starts eating a lot of your light at those wavelengths. Brimrose can do that (avoid fibers), but so can the FOSS / Perstorp 6500 (or whatever that machine is called nowadays). You will certainly find cheaper instruments based on filters or diode arrays, but check which wavelengths they cover! You should try to find out how difficult your problem is and spend money accordingly. I admit this is not easy! Location-wise you are obviously in luck, as most vendors will cover the US decently. | ||

Hello Michael, In chapter 21 of the 2nd edition of the "Handbook of Near-Infrared Analysis" Dr Tor P Schultz and I offered a chapter entitlied "FT/IR verus NIR: A Study with Lignocellulose" that might be useful to you. It identified four wavelengths (2262, 1828, 2010, and 2430) useful for analyzing lignin in pine. Don Burns, [email protected] | ||

Dear Michel The setting at this point is just a study because I'm a grad student at Texas A&M USA. The number of samples that will be processed in a month is a couple thousand. Whether the analyser is portable or not wil depend on the cost. I don't believe that it will be hooked up to a LIMS, SCADA or ERP system at this time. Can you please tell me what the advantages are of LIMS, SCADA of ERP system. What are the specifications that I should be looking for other than that it can analyze cellulose, hemicellulose,lignin, and protein. Thanks Ian | ||

Is it just a study? Do you plan on setting up routine analysis? How many samples will you be processing (per month)? Where are you based? (Not all vendors give good support worldwide.) Do you need the analyser to be portable, or online? What is your budget? Do you need to hook it up to a LIMS, SCADA or ERP system? The more info you give, the better we can point you in the right direction. | ||

Yes, i propose you to contact Brimrose Corp USA, they would bprobably help you with AOTF NIR analyser. Could be a good opportunity to analyse your product | ||

I wish to do NIR on sorghum stover and wish to determine the cellulose, hemicelllose, lignin, protein content. If some one could get back to me and recommend an NIR instrument to do this it would be greatly appreciated. |
