Give a detailed explanation of how Raman spectroscopy protocol will be used to process a sample of palm oil adulterated with Sudan IV
A sample of a liquid from an unlabeled bottle was subjected to analysis: MS showed that M+ has m/z of 89 and IR displayed bands at 2995-2840 cm-1, 1562 cm^-1, and 1425 cm^-1. Identify the functional group in the molecule and provide two possible structures.
heres the data TZ # Concentration Absorbance at 430 nmnm 1 33.6480 0.931 2 25.2360 0.757 3 16.8420 0.210 4 8.41200 0.137 5 4.20600 0.122
When we perform Bradford Assay to measure protein concentration, the spectrophotometer is set 595 nm because: a. the excitation peak of Coomassie Blue is best observed at 595 nm b. when Coomassie Blue binds to proteins, its maximum absorbance shifts to 595 nm c. the reducing effects of Coomassie Blue shifts the protein's maximum absorbance to 595 nm d. myoglobin is best observed at 595 nm
plese don't handwritten solution... What MS resolving power is needed to fully resolve the C8H8NO2 and C7H6N2O2 ions (at the base peaks)?
Imine compounds usually show stretching bands in the IR in the range of 1690-1649cm-1 and aromatic amines show a C-N stretch at 1340-1265cm-1. A related compound, N-benzylideneaniline, does not show tautomerism and has a C-N stretch at 1678cm-1 while H2SB-1(2-(2-hydroxybenzylideneamino)phenol ) shows a C-N stretch of 1590 cm-1. Given this information, does H2SB-1 show some C-N single bond character.
