Polish term or phrase: OD (skrót)
przy liście odczynników do chromatografii cienkowarstwowej niektóre odczynniki mają dodane OD
np. metanol OD, butanol OD, inne tego dodatku nie mają - chodzi przypuszczalnie o klasę czystości

ACS reagent


Explanation:
OD jest powiazane, jak Pan zasugerowal, z czystoscia odczynnika: do chromatografii cienkowarstwowej uzywa sie tych z najwyzszej klasy (ta technika robilem doktorat). OD w polsce ma oznaczac wlasnie to (pierwszy link).
Sigma-Aldrich, jeden z glownych dostawcow odczynnikow i chemikaliow na calym swiecie, opisuje swoje odczynniki wlasnie jako "ACS reagent" z podaniem czystosci (drugi link). ACS (Amerian Chemical Society) przy nazwie produktu oznacza tam wlasnie to, ze spelniaja przynajmniej ichnie wysokie kryteria czystosci. http://www.reagents.com/products/reagents/grades.html ewentualnie "ACS grade".

Mozna i "chromatography grade", ta fraza tez jest stosowana (http://tinyurl.com/bo89mzk) w odniesieniu do rozpuszczalnikow. "ACS grade" uzywa do podparcia swojej klasy bardziej ogolnych wytycznych, latwiejszych do wystandaryzowania (w zaleznosci od celu analiz, do chromatografii mozna uzyc odczynnikow rowniez gorszej jakosci, ponizej "ACS/chromatography grade").

Asker: czyli można by to ująć jako "chromatography grade", na podobieństwo "analytical grade" czyli cz.d.a

Asker: A jakie jest właściwie rozwinięcie tego skrótu?

Good luck!

All beyond my understanding, but I am hoping the references may be relevant to you, if not , apologies.
