Why do too densely coloured samples fail to give proper results using spectrophotometer?

Because we measure transmittance in spectrophotometer and for densely coloured samples transmittance will be very less. So we will not get proper results for absorbance.

Can a turbid sample be measured for absorbance in UV spectrophotometer?
Yes. Olis, Inc. (Bogart, GA) offers the CLARiTY line of spectrophotometers, which are specifically designed to give accurate absorbance readings in highly turbid samples.

Why are controls necessary when performing biochemical test?
Control samples are samples that someone has specifically created to have know concentrations of the compound(s) of interest. This includes blank samples with zero concentration. The Controls are mixed in with the real samples so the analyst does not know which are which. The analyses are conducted by standard methods and the results reviewed. If the work is done properly the values for the controls will be the same or within an expected range of variance as the known concentrations. The values of the real samples are then likely to be correct. This is a quality control or quality assurance procedure. Alternately the same samples can be sent out to a number of labs (Real and control samples). The results should be consistent. This procedure would identify labs that have consistently higher results for all samples. This process is called Round Robin testing
What happens when you mix urine samples to pass a drug test?
you'll get mixed results
What is the difference between convenience judgment and random sampling?
Non-probability or Judgement Samples has to do with a basic researcher assumptions about the nature of the population, the researcher assumes that any sample would be representative to the population,the results of this type of samples can not be generalized to the population(cause it may not be representative as the research assumed) and the results may be biased. Probability or Random samples is a sample that to be drawn from the population such that each element in the population has a chance to be in the selected sample the results of the random samples can be used in Statistical inference purposes
Can two different paternity test produce the same results?
If all the same samples and factors are used.
What indication do the experimental results give regarding the purity of the samples used?
After a detailed chemical analysis the purity is correctly evaluated.
How long does it take to get catecholamine test results back?
It may take up to a week for a lab to complete testing of the samples.
What could be a good bibliography for which brand of nail polish last longer?
Look and try out some samples and write FACTS about your results.
Do i say can i have samples about them or samples of them?
samples of them
Why did Mendel study such a large sample of pea plants to determine the probability of inheritance?
The more samples you use, the closer your results will match probability.
What experiments do geologists conduct?
I suppose hardness and density tests on rock samples. Making seismic soundings and measuring the results, analyzing the data collected.
