Cassin,
that is why I said in my orginal post that i just briefly saw the graphs, noticed they look different, and had to head off to class. if anyone is impulsive enough to throw their dutas in the trash and go pay $50 for a prescription that same minute, when I said i'd take more time to look at it later, after my classes that day, then that is their problem. All i'm doing is reporting my results, and I'm being very open about what i do and don't know and spent the last 4 or so posts explaining the possibilities.
Solo,
I was hoping a chemist would comment. I forgot you had a degree.
I don't know the brand, but i can go back to the lab and ask. Perhaps the software would be of importance too. It had a 6 inch long metal cylindrical probe like a straw about 1cm wide, maybe a little thinner. There is an opbical peice inside at the end. There are 3 fiber optic wires attached to the end which go into a box about 6 inches by 14 inches by 18 inches. The box just has an "on" switch, and two cables that go to a regular desk top computer. The box has two lamps, one for UV and the other for VIS, with 350nm being the switch point. It reades from about 170 nm to about 940nm, i think with tungston for the UV lamp.
I open the software with the mouse on the computer, which has windows 95. I dipped the probe in my 70% isopropyl alcohol sample and clicked "blank". It drew a flat line after about 15 seconds. Then I clicked "lock the blank", and dried the probe tip with a tissue between samples and tested each of the samples, first the avodart, then the dutas, then the elitenetavodart, and then duprost, just dipping and clicking "sample" each time. Very simple. Then I did the finasteride samples. At the end, I did the dutas again, and then dipped it into the blank to see if it still was flatlined. It had some noise as you can see. So I clicked "unlock the blank", clinked "blank" again, and then sampled the dutas again, getting the smoother graph.
For preparation, I put the finasteride pills each in plastic vials with 15 mL of 70% isopropyl alcohol and crushed them with a glass stir rod and let them settle for a few days in the fridge, and then pipetted the cloudy liquid out, leaving the powder behind. The finasteride samples all had a big round hump in the visual spectrum which I cut off, since i think that was white stuff we were seeing. i still have the full data set in excell.
With the dutasteride, i held the pills between the blades of a scissors, dipped into into the isopropyl alcohol, and cut them the long way, then stirred them for a few minutes and then removed the capsules with a tweezers. They sat at room temperature for several days before testing.
All solutions were prepared Thursday morning and tested tuesday afternoon.
I used the follow number of pills for each sample:
my elitenet avodart: 1
avodart: 2
aplunk1's dutas 3
my dutas 2
oldbaldy's duprost 2
dash's fincar 1
beaner's finpecia 2
beaner's finpecia 2
my proscar 1
my proscar 0.75 (about)
my proscar 0.5 about
I used my proscar to do the calibration. The software automatically expands the graph to fill the screen, and adjusts the axis, regardless of signal strength, so the lambda max is near the top, though it does not know the difference between lambda max a noise spike.
when I first saw the noise, I forgot the uv was supposed to be rounded, and i thought the dutas was off, and said this in my first post. when I looked at it again, I remembered and then corrected the post.
