if this works some posters are going to be pretty embarrassed. It's one thing to be wrong it's another to be loud wrong.
Still haven't seen one thing that proves it works :) People have units no one has proven it works yet. Would take a few minutes to load a couple samples and take a video, everyone's phone's have acceptable cameras now.

Pretty much everyone in this thread said that if they worked they'd buy one.

I'd rather have doubt and be proven wrong then to believe everything I see on the internet, this still sounds too good to be true.

Remember I called this! I knew they didn't have shit as far as a product went. This was a money grab, pure and simple. Nothing but vaporware.

If anyone who was interested in something like this, as was I, did the due diligence to research actual working products, one would find many concerning issues.
1. Models that are "Portable" haven't had the accuracy of a lab
2. This type of product would be revolutionary, not just for cannabis yet that seems to be the marketing point. I wonder why? Perhaps it's because stoners are a gullible group to pitch something any of us would actually have.
3. Their "team" has no experience that would make me confident they could even pull this off.
4. No patents
5. Not even setup as a legit company.

^TY's head is gonna explode if this gadget works^ lol
Dollars to donuts it isn't accurate. What's the point if it isn't accurate and comprehensive?

If I'm wrong, then I'm wrong and will admit such. I've got not issues of saying I was wrong. I've been wrong in the past, I'll be wrong about something in the future. The goal is to learn, not dig my heels in.

If anyone has a post of a video review, I'd be happy to watch it.

Good post. I feel the same way about new strains. I'd rather sit on the sidelines for a bit and see the reviews first before jumping in.


Remember I called this!
I don't think anyone will forget your position on this. lol

If I were a betting man I wouldn't bet against you on this one TY. I *hope* it works as advertised, but I won't be sold until I see some data that is backed up by lab tests from the same samples. Even if it's close (<10% margin of error) I would consider this a useful tool.

Agreed, when I checked them out a few months back it was still vapourware (still is imo) and their web site could have been built by my 6 year old grandson. Give us references, put them in the hands of some growers, compare the unit results against lab results, post all of that data so we can pick it apart, then I might consider forking out a few hundred bucks. Until then call me what you will but I'm skeptical...

instead of answering tonys questions, theyre just refunding his money and stated" this machine wont fit his needs." wtf!

this machine wont give you a test result, it compares your sample against their database i guess...
No shit? I wonder if that's the same deal as QuntaCann? It uses "near infrared spectrophotometry". I took a sample to a place in Ann Arbor and they had me test results in about 90 seconds. When I asked the guy how that's possible he told me basically what you mentioned above. It just compares your sample to the same strain in their database.

THAT'S NOT TESTING!!!!!

I think this pretty much puts this new portable bud "testing" technology to rest.

You have bubblegum, ok our database says bubblegum is 12% thc....

We are going to sit down and play with it tomorrow, It is not in my hot little hands at this moment. I do not think they are 25.99 each...

I hope it is not like a pokedex, That is what the youtube video reminded me of...

When I was looking the thing over it appears to be more then just comparing what you say you have and what the "database" says but wont know until I get to play with it tomorrow.

I would say the labs that have spent 100's of thousands of dollars for equipment for their labs should be the those who are embarrassed the most. Who would have known a few months later they could have gotten the same equipment for 25.99 portable? I am still waiting for PLENTY of confirmation. Showing numbers and being accurate are entirely two different things.
They were saying it's within 20% of lab work. That's not very good. However, that's good enough for me to be useful for my purposes. I'd like to know when I have certain cannabinoids at higher levels. You know, assuming it even works. They're also a few hundred, but still.

Yeah, my "25.99" is hyperbole, just pointing out the vast difference between the expense of the equipment labs are using compared to this portable. I also dont know 100's of thousands in the labs, once again just hyperbole pointing out the differences.

What cannabinoids and terpenes does the My Dx canna sensor purport to analyse ? Can someone please post a youtube video of sample insertion to end result.

Wah. It's gotta do something lol. Can someone please crack open their unit then so we can see the technology inside ?

Thanks for your interest in our QuantaCann technology. QuantaCann provides precise and accurate gas and liquid chromatography modeled results using a NIR Spectrophotometer and cloud based calibration set. The principal of analysis is molecular vibrational spectroscopy. Organic molecules have unique absorbances when irritated with light. Light is absorbed by the bond structure of the particular organic molecules; this is due to the resonation at particular wavelengths. The sample pattern of reflected light identifies the constituents. The intensity of reflected light positively correlates to concentrations of the constituents, in this case being major cannabinoids and moisture content. Our instrument records a unique spectral analysis of the absorbance of near infrared light on the samples it scans and calculates the value of THC and CBD in the GC model and THCA and THC in the HPLC model by accessing a living calibration via a network connection. Our technology is non-toxic, non-destructive (the sample is ground but safe for consumption) and nearly instant at 90 seconds. Welcome to the new frontier.

By the sounds of it the CDx is a handheld version of a similar type machine. If you can read past all the bullshit pseudo science speak they shine a fancy light at the sample, the sample absorbs light a certain way and it tries to find that in it's database and reports the results from the database rather then the sample. That's my understanding if I am wrong someone can correct me I am sure.
to answer your question regarding precision: The QuantaCann is inherently more precise than a Liquid or in this case a Gas Chromatograph for several reasons. To start with the sample preparation is far simpler. The sample is simply ground up, put in a cup and then scanned with light. In a GC the ground sample is weighed, extracted into a solvent, pipetted, transferred and finally injected into a heated column. All these preparatory steps are sources of variation which degrade precision.
Additionally, since the QuantaCann is spectrophotometer with only one moving part, several instrumental sources of variation are eliminated. These include oven temperature regulation, injector repeatability and column deterioration/contamination. A different but parallel set of error sources accompany the use of a liquid chromatograph.
That second bit is laughable, because it's not an actual test for potency it's more accurate .... but it compares to the "less accurate" type of testing that they have recorded in their database. So wait a minute.... IF GC is not accurate or has all these failing points why would they have a database full of GC data that they then relay to the customer... I'm so fucking confused right now. THIS IS REGARDING THE QUANTACANNA machine. It's more accurate because there is less science and more guess work, I guess.

If I was looking for a portable testing I'd look into the guys making the little vials that change colour, I forget what they are called right now. But they can't be nearly as expensive and they actually test your sample rather then giving you test results from some guys sample in California. They have a THC and CBD test, no idea how accurate they are there are people testing them now I think. I would have more faith in that product.

I want to see a moldy sample loaded and see if it can at least do that.

My Dx purports to use alternate technology - the electronic nose. The sample is vaporized and sensors are triggered according to the cannabinoids/terpenes present in the sample and a strain profile can be generated. Yes their sensors must be intially calibrated against something else initially ie GC results, but it seems really illogical and fraudulent to go back to a preset database to calculate each subsequent result after the initial calibration. I'm not saying the My Dx actually works (or does what it says) but that's how it was advertised and the core technology is out there so I'd like to see with my own eyes what it actually does. I've been following this project quite carefully and am familiar with other test methods available like TLC (thin layer chromatography), spectrophotometry, immuno-assays and of course HPLC and GC.
