Talk:Paper chromatography

Wikiproject Law Enforcement

I removed the WP:LE tag because the article is about a complicated scientific proceedure that does not have any law enforcement content.EMT1871 16:28, 3 February 2007 (UTC)

I am doing this project for school! We needmore information here.

I need to know how picture chromatography works for school and i dont understand. i need more information!!!!!! —Preceding unsigned comment added by 212.44.35.5 (talk) 18:58, 7 October 2009 (UTC)

Check up on Thin Layer Chromatography which this basicly is... both pages (TLC and PC) should be merged... they are the same. I do forensics and we use paper or the glass slides so the WP:LE tag should be left in. —Preceding unsigned comment added by 152.71.41.170 (talk) 02:36, 10 June 2010 (UTC)

Will results vary if we use different kinds of paper?

I'd really appreciate it if someone could answer this question for me: Will the results for a paper chromatography experiment vary if we use different kinds of paper? I mean will the ratios between the lengths of the bands differ in such differing scenarios using different types of paper? Thanks in advance. WinterSpw (talk) 02:43, 30 November 2009 (UTC)

It's likely to be different. For reproducible results, you need to use the same paper. --Rifleman 82 (talk) 03:40, 30 November 2009 (UTC)

Techniques in greater detail

In case of the pigment and solvent initial points being different (For example: paper dipped to solvent 1cm deep, but the pigment dot is at 3cm.), is the correct way to measure the solvent front from the pigment dot, from the surface of solvent or from the beginning of the paper? (In given example, measuring started 3cm, 1cm or 0cm from the bottom of the paper, respectively.) --88.112.41.113 (talk) 15:21, 15 June 2011 (UTC)
dude i am is in fsc(med) and i want to ask this question to my teacher plz help me ahahsanislah@yahoo.com — Preceding unsigned comment added by 111.88.34.160 (talk) 02:49, 21 October 2011 (UTC)

Hi! You want to ask this question to your teacher? And you need additional background information? Well, you need to ask the question at Wikipedia:Reference desk/Science (click the button Ask a new question). Explain what steps you took to find the answers yourself, in as much detail as you can; what problems you had finding the answers you needed, in as much detail as you can; and then why you need these particular answers. --Demiurge1000 (talk) 03:02, 21 October 2011 (UTC)

what is that second sentence?

the second sentence in the intro:

"Erwin Chargaff credits in Weintraub's history of the man the 1944 article by Consden, Gordon and Martin with sparking his discovery of Chargaff's rules, an important precursor to Watson and Crick's discovery of the double-helix structure of DNA,[2] for which they were awarded the Nobel Prize in Physiology or Medicine in 1962."

seems out of context, and quite frankly i'm lost. does it belong in this article? 76.100.209.236 (talk) 06:59, 28 December 2021 (UTC)

It does not appear to belong in this article. I have removed it. Thanks JimRenge (talk) 15:39, 28 December 2021 (UTC)

Applications

This technique is apparently used in rapid home COVID tests and home pregnancy tests. This should be mentioned. Vanzandtj (talk) 13:58, 7 January 2022 (UTC)
