Quantitative Analysis of Different Formation Modes of Platinum Nanocrystals Controlled by Ligand Chemistry [PDF]
Nano Letters, 2017 Well-defined metal nanocrystals play important roles in various fields, such as catalysis, medicine, and nanotechnology. They are often synthesized through kinetically controlled process in colloidal systems that contain metal precursors and surfactant molecules.

Recent advances in quantitative LA-ICP-MS analysis: challenges and solutions in the life sciences and environmental chemistry [PDF]
Analytical and Bioanalytical Chemistry, 2015 Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) is a widely accepted method for direct sampling of solid materials for trace elemental analysis. The number of reported applications is high and the application range is broad; besides geochemistry, LA-ICP-MS is mostly used in environmental chemistry and the life sciences.

Evaluation of a semiquantitative SNAP test for measurement of bile acids in dogs [PDF]
PeerJ, 2014 Background. Serum bile acids (SBA) are used as a routine screening tool of liver function in dogs. Serum samples are usually shipped to a referral laboratory for quantitative analysis with an enzymatic chemistry analyzer. The canine SNAP Bile Acids Test (

Quantitative physical chemistry analysis of acid−base disorders in critically ill patients [PDF]
Anaesthesia, 2001 Compared with the Henderson−Hasselbalch approach, the Stewart approach may better describe the mechanisms of acid−base physiology and disorders. We prospectively examined the acid−base disorders of 100 routine blood samples from critically ill patients using Stewart's physical chemistry analysis.

Analytical Chemistry by Means of Oxalic Acid. I. On the Quantitative Analysis of Strontium [PDF]
Bulletin of the Chemical Society of Japan, 1952 Abstract 1. Quantitative precipitation of strontium as its oxalate monohydrate is made possible by employing 50% alcohol as the washing solution and by drying the precipitate at 100–105°C for 2 hrs., and as a consequence a new method for determining strontium gravimetrically was established. 2.

FLow-injection analysis: a new approach to quantitative measurements in clinical chemistry.
Clinical Chemistry, 1982 Abstract Flow-injection analysis, founded on an approach that is entirely different from continuous-flow analysis, involves use of three principles: sample "injection," controlled dispersion of sample (rather than a dispersion retarded with gas bubbles), and reproducible timing.
