Are your blanks intended to mean “none” or are you just not suggesting answers for them?

Organic Spectroscopy / Re: Polyethylene bands at 1539 and 1575cm-1?
« Last post by marquis on Yesterday at 04:30:20 PM »
It sounds like most of the ingredients have been covered.  The one ingredient not totally covered is Polyethylene.  The one warning about polyethylene.  There are many varieties( high density, low density, different molecular weights, different branching structures, etc.).  Most routine testing will not show these differences.  If further testing is required, you might investigate something like gel permeation chromatography(GPC). Because it's PE, it has to be done at something like 160 C with some not so nice solvents. Good luck.

Ok.  So... You think the wine amber color material is actually byproducts and not nickel or aluminum ions?  I don't get any colored reaction forming if include KOH in the reduction solution.  I'll try ammonia in methanol and see if this helps.

Raney-Ni reductions of nitriles are not straightforward, often people uses 2M NH3 in MeOH to suppress side reactions. You can try Alumina plates for TLC or use RP-plates, usually there is one method to purify that works, you can run RP-column or Alumina-column chromatography. You have amines and to add TEA to a silica-TLC system can also make separation better.

Well, to begin with, you do not start pumping gas and turning the electronics on until the whole system is under high vacuum, i.e. the vacuum pumps (roughing pump and hv pumps ) have been on usually overnight.
1) pump down to around 1x 10 to -6 mm
2) electronics ON
3) Gas flows ON
4) set temperatures of source etc.
5) Allow 4 & 5 to stabilize
6) Infuse a solution of your tuning compound
7) Optimize the signal over your range of interest (m/z 200 -700)
8) Enter your method descriptor (scan m/z 200-700, generally 1 sec)

Let us know if this works for your system.
