- This theory maintains plate theory theres a theoretical division into plates but it says that the gaussian shapes of chromatographic peaks can be explained by the random motions of the. Use this information to answer the question below Length of column 3050 cm Flow rate 0313 mLmin A chromatogram of a mixture of species A B C and D provided the following data. The zone broadening within a perfectly packed bed is well understood and standardized efficiency test protocols are established and in use 13A dimensionless.

The height equivalent to a theoretical plate as discussed above is defined as the proportionality constant relating the standard deviation and the distance traveled. A chromatography column having which of the following plate heights would be most efficient. They have decreased plate heights.

Plate height Reduced plate height Plate number. HETP σ 2 L in which σ is the standard deviation and L the distance traveled. Within each segment equilibrium is supposed to exist.

The bed heights are usually from 10 to 30 cm regardless of column diameter. This equation relates the efficiency of the chromatography procedure to three different factors. N 2 7504.

The resolution calculation based on the. Since k and a do not change with column length Equation 413 indicates that the resolution is proportional to.

If you cant find your institution please check your. View the full answer. The resins are expensive and can be difficult to work with.

The goal of chromatography is to separate a mixture into a series of chromatographic peaks each representing a single component of the mixture. Several definitions used in size-exclusion chromatography are added Distribution constant Retention time of an unretained compound Total mobile phase time The following definitions are also added. The resolution between two chromatographic peaks RAB is a quantitative measure of their separation and is defined as.
