The pH value, soluble chemical oxygen demand (COD), volatile fatty acids and total inorganic carbon (VFA/TIC) ratio, and biogas composition were examined using standardized cuvette or titration tests and online monitoring equipment.
The used BioLogic (Grenoble, France) stopped-flow equipment permits automatic titration and repeated technical replicates, which typically yield a small standard deviation.
This sensitivity level, along with other features of the equipment, particularly a "gas-phase titration" routine for changing the cell composition, makes it effective for the investigations of several types of biopolymer interactions.
This method mainly involved digestion, distillation and titration (Kel-Plus, Elite Ex 8L, Pelican equipments, India).
Accurate titrations require clean, precise, professional-grade chemical equipment.
Titration resulted in a secure and inexpensive method if compared with the equipment-dependent and more expensive CHN elemental analysis [9].
Field parameters pH, temperature (T), electrical conductivity (EC), redox potential (ORP) and dissolved oxygen (DO) of samples were measured by portable equipments (Horiba, Japan), and alkalinity was determined using the acid neutralizing titration on site.
I could spout the titration of his meds.
Antibody titration takes ~4 h.
Titration curves were analyzed using ORIGIN (OriginLab).
