Minitat's take on the Resolving Power matter.
"I believe the piece actually says a lot.
Resolving Power, as applied to a spectrum of analysis, is the ability of a spectrometer to separate 2 adjacent peaks in a spectrum. To determine recency of use, it is easier to identify more powerful concentrations of a substance closer to the actual time of use. As time passes from initial usage, the intensity of the substance decreases and is therefore more difficult to determine exact time of usage within an acceptable margin of error.
My takeaway is that BLO has the recency of use nailed to within the generally accepted 2 hour recency of use window. I believe that they are further refining that recency of use to go beyond 2 hours, when the analysis becomes harder due to deterioration of the substance of interest. Instead of just good enough, I believe their goal is to exceed the standard
As federal rules and regulations are modified to to determine impaired scales of marijuana use at 1 hour, 2 hours, 2 plus hours (to mimick blood alcohol deterioration), I believe BLO is leaning forward to have their device accurately capable of resolving power issues well beyond 2 hours - to benefit LEA field usage and the legal system.
Furthermore, the fact that there is a short list of 2 medical eqipment manufacturers stated, BLO is closer to field testing than I had previously thought. When a company puts out a a tender for equipment, the competitors will respond with prototypes for the company to lab test and determine compliance with the statement of requirements. I believe that BLO likely has these prototypes in hand and field testing will be done with (a) both devices if they are closely matched, or (b) the preferred device if it is clearly superior to the other device.
I believe the next NR will be a combined (a) testing complete and (b) partnering manufacturer announced, and it will be sooner rather than later.
All of the above my opinion only from reading/dissecting the BLO NR's and progress updates"
