|PROJECT TITLE:||Solvents Characteristics : CHLOROFORM (CH.CL3)|
|RELEASE DATE:||05 Feb 99|
|LAST UPDATE:||2 Sep 2009|
|VERSION HISTORY:|| 1.0 - First release |
1.1 - Revision of text and formatting. (2-Sep-2009)
|Solvent:||TRICHLOROMETHANE (Chloroform) - ( CH.Cl3)|
|Concentration||Absolute (100% c. )|
|Flow Rate:|| 45% in 10mins
75% in 35mins
Extremely soluble, leaving minimal colour in the application point even after 10mins of treatment. This also means that all components of the ink are completely soluble in this solvent.
|Separation of dyes:|| 0/10
No separation at all. Just an enlongated streak of a blend of both colours.
|Allocated Time:||Not more than 40 mins|
|Comments:|| This forms an enlongated zone from the point of aplication
up to the level of solvent in the strip. The streak shows no
signs of separation, which makes this solvent score low at
this absolute concentration.
On leaving for a long time, hence till 85% of the strip, the violet dye seems to gather and gets concentrated as a rough line at the top edge the solvent raised in the strip. This results in making the rest of the streak more in the cyan blend (since the violet dye gets concentrated above.) However there is still no separation properties.
|BEST Separation:||Absolute Chloroform for not more than 40mins, although no true separation is achieved!|
|Note 1:||Very fast solvent, ideal for a quick overview before applying the chromatography in more specific solvents.|
