The following is a guest post byParker Bennett. Parker is a bit of a regular around here, known for tackling common problems with unique solutions. This time he’s back at it creating complex shapes that have image backgrounds, shadows, and curves, yet are flexible. I love to collaborate ...
Santa Clara, CA USA Volatile Organic Compound Analysis Using Purge and Trap Success with VOC analysis using the Agilent 5975C Mass Selective Detector Application Note Environmental Abstract Despite the status and widespread application of Purge and Trap (P&T) with GC/MS for volatile organics, ...
8.0 min and 15.0 min in mobile phase B. To establish the intermediate precision, another analyst prepared and determined PCC in three solutions of different concentrations. The RSDs ≤1.4% are satisfactory. The detection limit depends on two parameters, such as the composition of the ...
Dissolved organic matter (DOM) represents a key component of carbon (C) cycling in freshwater ecosystems. While the behaviour of bulk dissolved organic carbon (DOC) in aquatic ecosystems is well studied, comparatively little is known about the turnover o
BINDING ASSAYS: RAPID, LABEL-FREE SOLUTIONS FOR CHALLENGING PROBLEMS Many drug discovery programs seek small molecules that bind a specific target. When binding does not change functional activity or the target itself does not possess enzymatic activity, binding assays must be developed to reveal small...
For the spiked tea samples, it is also necessary to add a certain amount of iso-propanol standard solutions to the above-mentioned ATPS. The mixture was placed in an ultrasonic bath, extracted at 40 °C for 20.0 min, allowed to stand at 40 °C for another 30.0 min, and then ...
The percent drug released was then calculated using a calibration curve generated by measuring the absorbance of standard solutions of R5000 at 285 nm. A 285 Corrected = A 285 Measured - ( A 370 Measured - A 390 Measured 370 - 4 - 390 - 4 ) ...
The present invention has been made in an effort to solve the above-described problems and intends to provide a novel intramolecular rotation-enabled two-photon fluorescent probe compound in which a twisted intramolecular charge state (TICT)-based fluorescence quenching pathway is introduced, which resu...
Solutions of monomeric trivalent antimony-tartaric acid compounds having a molar ratio of antimony to tartaric acid of 1 to 1 to 2 to 1 stabilized with an anion such as chloride in certain polar organ
On stability of solutions of compound boundary value problem for the perturbation of boundary curves; 复合边值问题的解关于边界曲线摄动的稳定性 2. The stability of the general compound boundary value problem for bianalytic functions about boundary curve 双解析函数的一般复合边值问题关于边界曲线的稳定...
