Sentence examples for analytical traces from inspiring English sources

The crude peptides were purified by preparative reverse phase HPLC on a Gilson instrument with a Phenomenex Jupiter Proteo column (10 μm, 90 Å, 250×21.2 mm, 20 mL min−1) and eluted with a linear gradient of 5%to25%25 % B, where B is acetonitrile+0.1 % ammonia and A is water+10 % B. Analytical traces and accurate mass data were obtained to confirm purity.

Analytical behaviorism traces its historical roots to the philosophical movement known as Logical Positivism (see Smith 1986).

Unless otherwise noted, all preparative runs used linear gradients of 30 60% buffer B in A (A: water containing 0.1% TFA, B: CH3CN containing 0.1% TFA) over 30 min. Analytical HPLC traces of final products were performed on a Gilson HPLC system with 220 and 254 nm UV detection, using a Varian Microsorb 100-3 C18 (100×4.6 mm) column at a flow rate of 0.7 mL/min.

All chemicals and reagents used in this study were of analytical and trace metal grades.

A representative analytical HPLC trace is shown in Fig. 2 ([18F]AV1451 tR = 13.2 min) and with an overlay of the UV trace of the reference standard in Fig. 3.

The combination of a Monte Carlo-based forward-projector and a simplified analytical ray-tracing back-projector produced quantitative images of acceptable image quality.

A deep analytical ray tracing study has been made of the design characteristics and concentrator performance, thus determining the configuration which optimises efficiency.

The great advantage of an analytical ray tracing library is the numerical precision of the quantities computed and the fast execution of the implemented codes.

Following the analytical ray tracing through the GIGL model, we shall derive the expressions for the axial and lateral color coefficients.
