TIDA-00155: DLP Near-Infrared Spectrometer performance low concentration aqueous samples

Silje Fuglerud

Part Number: TIDA-00155

Hi, 

To assess the performance of the DLP NIR spectrometer, I am looking for example studies of aqueous samples of low concentrations. Does anyone know of any literature on this application?

    Silje,

    Welcome to the forums and thanks for your interest in our DLP products.

    I don't believe we have application notes of this specificity on TI.com. May I ask what your target application is?

    Hi Philippe, 

    Thanks for your help!
    Is there any examples of the DLP Near-Infrared Spectrometer for Optical Analysis of Liquids & Solids Reference Design being used for any aqueous samples at all? If the cuvette is about 1 cm, I guess the water absorption would overshadow anything else. But some signal could probably be obtained if the cuvette holder and tungsten lamp was replaced by something else with a shorter optical path length through the sample. So I guess my question is if this was ever done (to your knowledge)?
    I am interested in using the TIDA-00155 for in vitro screening of aqueous samples with constituents that have features in the 2000-2500 nm wavelength channels (in the water dip). 
    Regards, Silje

    Silje,

    In speaking with my team, I don't believe we store data of this nature on TI.com. You may need to inquire with a third party supplier who is more specialized for this inquiry.

    I apologize for the inconvenience.

    Hi Philippe,

    That's okay, the application is not common with these types of spectrometers.
    Would it be possible to contact one of the NIR engineers directly? I would want to exchange the cuvette holder and bulb and would very much appreciate any tips and possible pitfalls. And doing that, how much power can the mirrors hold?

    Best regards,
    Silje

    Silje,

    What do you mean by exchange? I'll see if there are any of my colleagues I can get you in touch with.

    Best Regards,

    Silje,

    I haven't had much luck in finding assistance for you at this time. Do you still need assistance with this issue? Let me know.
