Περιγραφή
Practical paper chromatography offers motivational learning opportunities, but relies on standard analytical grade papers or much less satisfactory alternatives such paper towelling.
Using, for example, a mixture of CMY inkjet printer inks the card will produce a separation column up to 50mm in length in approximately 5 minutes. A whole class set of 100mm long spills can cost less than a single analytical grade equivalent spill
Applications include: basic chromatography separation, forensic techniques, stain diffusion patterning, colour diffusion patterning, records of chemical reactions, fluid syphoning – i.e., how to empty a cup with a bent wick!
The material is supplied in packs of 10 (approximately) A4 size sheets and an instruction sheet.
