- In the Thermo Fisher application note about wine analysis (Lesson 3), the following chromatogram was collected of nine components of wine. If peak 3 has a retention time of 3.15 minutes and a peak width of 0.070 minutes, and peak 4 has a retention time of 3.24 minutes and a peak width of 0.075 minutes, what is the resolution factor between the two peaks?

Composite materials can only be: metal-polymer or polymer-polymer.(B). Composite materials can be made up of particles, but not fibers or sheets.(C). When the reinforcing particles are uniformly distributed in a composite material, there may be a greater tendency for it to have isotropic properties.(D). None of the above is correct.arrow_forward
