coefficient de DO ? Explanation: "coefficient de dissolution" as a chemical term exists in French, but its abbreviation is Kd ... please see URL : http://www.inrs.fr/dossiers/amiante/te46-ad.htm where you can find : (see Kd at the bottom) TABLEAU VII Essai indicatif de classement des FMA en fonction de leur solubilité in vitro et de leur biopersistance (Exemples chiffrés repris d'un document communiqué par M. BIGNON). Biopersistance Remarques et exemples (1) Très biopersistantes, très peu biosolubles, T1/2 > 60 j Fibres hautement réfractaires KI = - 90 ; Kd < 6 ; KNB < 2 Exemple : RCF1 (2) Biopersistantes, peu biosolubles, 30 j < T1/2 < 60 j Fibres pour le renfort; elles ont souvent un diamètre supérieur à 6 micro-m. KI # 2 ; Kd # 8 ; KNB # 3 Exemple : verre E Fibres spéciales pour la filtration. KI # 20 ; Kd # 11 ; KNB # 16 Exemple : fibre 475 de Schuller Fibres pour laines d'isolation - 5 < KI < 5 ; 6 < Kd < 30 ; KNB > 18 Exemples : laine de roche, MMVF 21, basalte (3) Peu biopersistantes, biosolubles, 15 j < T1/2 < 30 j Fibres pour laines d'isolation 20 < KI < 30 ; 30 < Kd < 300 ; KNB > 18 Exemples : laine de laitier, laine de verre, MMVF 10, MMVF 11, MMVF 22 (4) Très biosolubles, non biopersistantes, T1/2 < 15 j Fibres nouvelles pour isolation KI > 30 ; Kd > 300 ; KNB > 18 Exemples : CM 25, TM 34 [HTX] Kd = Coefficient de dissolution in vitro en ng.cm-2.h-1, pH = 7,4 Sorry for "negative answer" !!

OD coefficient Explanation: DO = Densité Optique = Optical Density This is a measure of the light absorption properties of solutions (or solids, but from the bunch of questions you ask I think that it's all about dissolution tests with UV-VIS or IR spectrophotometer). Coefficient = coefficient (in physics at least). By the way you are somewhat right in your interpretation becaus the optical density is also related to the dissolution factor I hope I could help you.

OD coefficient Explanation: I am 100% sure that the answer I have given is right if the context is optical measurement during a dissolution process/state : before turning to translation, I was an analytical chemistry application engineer. I perfectly know what is dissolution coefficient and it is noted Kd. This coefficient can be measured by measuring the Ph but also by measuring the optical density of the solution. Would you be so kind to send me a small mail with more context? I could probably better help you. 25 years of analytical instrumentation |
