What else can I help you with?
How do you know if a sample is more contaminated than other?
You can determine if a sample is more contaminated than another by comparing the levels of contaminants present in each sample. This can be done through analytical testing methods such as chemical analysis or microbiological testing. The sample with higher concentrations of contaminants is considered more contaminated than the sample with lower concentrations.
How does a light scattering detector work in the context of analytical instrumentation?
A light scattering detector in analytical instrumentation works by measuring the amount of light scattered by particles in a sample. This scattering pattern provides information about the size, shape, and concentration of the particles in the sample, helping to analyze and identify substances present in the sample.
What is the function of a hollow cathode lamp in analytical chemistry techniques?
A hollow cathode lamp is used in analytical chemistry techniques to produce specific wavelengths of light for atomic absorption spectroscopy. This lamp helps to excite atoms in a sample, allowing for accurate measurement of their concentration in the sample.
What branch of chemistry carries out tests to identify an unknown substance?
Analytical chemistry is concerned with investigation of the quantitative and/or qualitative characteristics of a given sample. For instance, an analytical chemist may qualitatively determine what the various polycyclic aromatic hydrocarbons in a tar sample are, and may also quantitatively analyze the concentrations of each species in the sample.
Liquid and gas sampling analytical chemistry?
Liquid and gas sampling in analytical chemistry involves collecting representative samples for analysis, typically using techniques such as syringes, pipettes, or gas collection bags. The collected samples are then analyzed using various analytical techniques to determine the composition and concentration of substances present in the liquid or gas sample. Proper sampling techniques are crucial to ensure the accuracy and reliability of the analytical results.
What are the sample problems for graphical and analytical method?
Graphical method sample problem: Find the solution to the system of equations: 2x + 3y = 12 x - y = 3 Analytical method sample problem: Solve the system of equations using substitution method: 3x + 2y = 11 4x - 5y = -7
Why the sample storage is one of the important steps in an analytical procedure?
Simply because it may be some time before the sample arrives back at the lab. Furthermore, if you collect it in a container that is not adequate, you may introduce contamination on sampling. Decomposition may be an issue also, if stored incorrectly.

What is the branch of chemistry which study the composition of a sample?
This branch of chemistry is called analytical chemistry.

What is the Correct procedure for handling sample of pond water?
place the sample on the microscope slide and observe it.
Distinguish between a gross sample and a laboratory sample?
In geology say, a gross sample would be a representative sample of the whole rock. A lab sample would be a fraction of that, refined such that measurements are able to be made on a single mineral. for example, a piece of basalt would be a convenient field (gross) sample, from which say, mica is extracted after grinding and separation, to enable the 'date' of the basalt to be determined. Similar concepts would apply in other fields, such as biology, botany, water sampling and so on.
Why we are choosing plasma matrices in bio analytical sample preparation?
because it is the matrix in which circulating analytes reside
What is the object of sampling operation in analytical chemistry?
The purpose is to obtain a statistical representative sample from the material to be tested.
