Pocket SCiO Spectrometer Sends Chemical Composition of Anything To Smartphones 82

MojoKid writes: Is that a tricorder in your pocket or are you just happy to see me? All joking aside, the handheld SCiO could truly make you feel like a member Bones McCoy's medical team. The SCiO turns science fiction into science fact by shrinking mass spectrometry technology used in traditional lab settings into a device small enough to fit in the palm of your hand. While pricey handheld spectrometers have been available for researchers, the SCiO is the first such device marketed directly at consumers. To get the SCiO down to a reasonable price point, Consumer Physics uses near-IR spectroscopy and optics typically found in smartphones to measure the light reflected from any given object. Held at a distance of 5 to 15 mm from the intended target, SCiO captures reflected spectrum data and uploads it to its own cloud platform. The company's proprietary algorithms then analyze the data and send the information back down to your smartphone (SCiO require a Bluetooth connection). Reportedly, this whole process occurs within 1.5 seconds. The hope is to empower consumers to learn more about the world around them and even about the things that we put in our mouth. You'll be able to ascertain nutritional information about the foods you eat without having to rely on labels, or even determine the ripeness of fruits and vegetables with the push of a button. The Whole Foods crowd will be all over this, one would think.

      You're right, this article is garbage. This may or may not be a neat device and may or may not be capable of doing cool things but you need to go somewhere else to find out. Mass spect would be cool but without some kind of separation up front for all the components, it would just give noise. I don't think they've figured out how to get mass spect this small. Near-IR also sounds suspicious. As an organic/analytical chemist all my life, we've used spectroscopy from radio waves (NMR) to x-rays (crystallogra

          Come on AC, be nice. You can't use near-IR to identify unknowns when you have a nearly infinite number of possibilities. There are devices for monitoring reactions using Near IR, but their use requires intimate knowledge of the contributing components and calibration of each one. If some new unknown shows up you don't get enough information from their near IR absorbance to assign identity. I 've been doing this stuff for 40 years so I don't need to read the wiki article and become an instant expert like you. However, I will read the wiki article and see if I can understand why you've been mislead.

          I just looked at the article. You owe me an apology.

      Of course not - in fact, already the headline should arouse suspicion that somebody in the chain of communication hasn't got a clue: "... chemical composition of anything ...". There no instrument at all in existence on this planet capable of doing this. It may be reasonably easy to measure the relative abundances of chemical elements and their isotopes in a sample, but not with a simple 'near infrared spectrometer', I would have thought, and as for analysing such a spectrum to get the 'chemical composition of anything', the fact is that there are millions or billions of common molecules arounds - such as proteins - and we do not have any simply understanding of what their spectral fingerprint might be. Single atoms have well-defined, discrete spectra, but complex molecules may not even have discrete spectra.

      On top of that - even if we were able to calculate and measure spectra perfectly, and assuming that the very limited 'near infrared' bandwidth is sufficient to distinguish all molecules, the analysis part is likely to require massive processing power. All in all - a load of hyped up nonsense.

        Think of it like a camera. It has limited wavelength response, limited resolution, and computing anything from the images is really really hard.

        But until you have the camera, you won't get face recognition or object tracking or AR or Deep Dream, and once you have the camera and it's cheap and processing power increases sometimes you can be amazed at what can be done within its limitations.

    Designing spectrometer is what I do for a living and with my experience and knowledge, I have serious doubts this device has sufficient resolving power to do what they claim it can/would/should do. To identify chemical components, you need a minimum spectral resolution (depending on the species you want to identify). To do quantitative analysis, the requirements are event higher. Typically, for solid NIR spectroscopy, I would aim at 2 to 4 cm^-1 spectral resolution. Under this, you can maybe check for the presence of a specific compound or compound family, but the capability to do so will be very dependent on the overall chemical composition.

    Its possible to reduce the size of a spectrometer while somewhat keeping the resolution. But that goes only up to a certain extent... and that goes only with trade on signal to noise ratio. At some point physics overtakes wishful thinking. Reducing the instrument, and thus the optical throughput, you need longer measurement times to achieve adequate signal quality. Quantitative analysis with a (large) lab NIR spectrometer can take minutes, depending on the material being analysed. When you design spectrometers, you are constantly trading on aspect for another and by bringing a NIR spectrometer to that size, you traded a LOT of stuff away.

    I also see spectral calibration being an issue with this device, then it works in reflectance and not in transmittance. It cannot be self-calibrating and directly provide a transmission/absorption spectrum. Maybe it is calibrated once during the production and assumed to be stable? If that is sufficient is, from my experience, questionable.

    On the other hand, this is a very exiting breakthrough. I might even get my hands on one for fun. Why? because its, as they so well market it, a liberalisation of matter. Its a first step in being able to identify any substance that we get our hands on. While it may not yet be able to provide a full chemical make-up of a product, with enough a priori information it may be very useful.

    Let me give you an example where such a device can be its money worth. When you buy fruits and vegetables that are bio/organic, you want them really to be that way. This decision to spend more money on these healthier food items is solely based on trust, which is often exploited. I doubt that the analysis of such a product can do what they claim (most of the return information is most likely deduced from the a priori information provided). But even with a limited spectral resolution and sensitivity, it should be able to identify spectral signatures of typical herbicides and pesticides.

I guess that why the cloud db is there, its not so much doing analysis and working out what the thing is from its consituents, but matching the signal it gets with a db of things that have been scaned by tbe device that are already known.

        Don't expect to much of it for the first generation / first product. Once you get a few competitors and iterations on the technology, you can have a serious look at it. I'd also wait to see a view "in-depth technical reviews" with labor-based comparison studies. To satisfy your curiosity, if your budget allows it, it will definitely be worth it (assuming it at least work a little).

      I would be amazed if it could. With a sufficiently large database to draw from, and clever processing, I can imagine being able to identify the bulk constituent, but anything else would be lost in the noise. It might be able to tell you if your apple is waxed or not, but not if it's got ppm levels of pesticides. TBH, I'll be pretty impressed if this could identify different plastics or other relatively pure materials. It is certainly a nice idea though.

        There's a reason IR spectroscopy has fallen by the wayside in chemistry - it doesn't give you enough information, and just hasn't kept up with other techniques. It's used for specific tasks, such as monitoring a reaction, but it's not a go-to analysis technique any more.

        I couldn't disagree more (although one would say I'm somewhat biased on the applications of IR spectroscopy). First I know no research or production analytic lab without at least one IR spectrometer. In quality insurance they are also used a lot. For in-situ monitoring of reaction, IR spectrometer are generally not appropriate because to slow at sufficient spectral resolution. You can only monitor very slow reactions.

So, yeah, it should be a whole separate unit that is attached and used through an existing phone.
