The model consists of a BCS-like term in the Hamiltonian and the Anderson impurity treated in the self-consistent large-N mean field approximation. Increasing impurity concentration or lowering the ratio drives the system through a transition from a state with two sharp peaks at low energies and...
Resins swollen in deuterated and protonated solvent are studied. Use of the LED sequence eliminates the peaks due to the use of protonated solvents, but sensitivity is decreased, and differential losses of magnetization might lead to a biased population estimation. However, as all sample workup ...
AV has pKa value 5.54 hence, the buffer pH was set between ±2 of pKa; as in that range nearly 100% of the drug is ionized or unionized which is suitable for better seperation. A further change in the organic phase ratio affects degradation peaks retention time and column temperature ...
This activity is often performed using a combination of NMR and LC-MS/MS. Although modern nominal mass LC-MS instrumentation, such as a tandem quadrupole or ion trap mass spectrometer, can quickly produce high-sensitivity, fast scanning data, the interpretation of its ...
the retention time of the compound in HPLC allows for setting a relative retention time, thus making qualitative analysis possible. The concentration of the compound in solution before injection into an HPLC column allows for comparison of the areas under the peaks in an HPLC chromatogram, thus ma...
Mass spectrometry for the most part eliminates co-eluting peaks because we can focus in on a mass transition for the compound of interest, but there are still times when compounds share the same transitions or have cross talk with transitions from other compounds. Extraction techniques have ...

No other peaks were detected in the radioactivity channel. Figure 2. Typical γ-HPLC chromatogram (method 1) of [177Lu]Lu-PSMAI&T with main product (Rt = 4.20 min) and radiolysis-induced side product (Rt = 3.88 min). Depending on the AC, the integral of the impurity was rising, ...
Rapid elution of all the substances, both active substances and impurities, present in the multicomponent sample; (iii) High selectivity with excellent chromatographic resolution between adjacent peaks. After establishing a fundamental aspect of impurity analysis, namely the specificity, it remained to val...
