What does aliquot volume mean?
Aliquot of a sample, in chemistry or the other sciences, an exact portion of a sample or total amount of a liquid (e.g. exactly 25mL of water taken from 250 ml)
What do you mean by aliquot?
1 : contained an exact number of times in something else —used of a divisor or part 5 is an aliquot part of 15. an aliquot portion of a solution. 2 : fractional an aliquot part of invested capital.
What is the aliquot of a sample?
An aliquot is a type of sub-sample that is taken or extracted from an original sample. If we think of fractions, we can compare aliquots to the concept of part and whole. That is, an aliquot is the fractional part of an entire whole sample. Generally, aliquots are associated with liquid-based solutions.
What is the difference between aliquot and sample?
is that sample is a part of anything taken or presented for inspection, or shown as evidence of the quality of the whole; a specimen; as, goods are often purchased by samples while aliquot is (chemistry|biotechnology) a portion of a total amount of a solution or suspension.
What is the process of Aliquoting?
Aliquot means to separate a portion of the serum or plasma and place in a separate tube. 2. Plasma is the required specimen b. There is no gel separator to separate the serum/plasma from the cells c. Stability requires this done before transporting to the laboratory.
What is an aliquot used for?
When a drug or alcohol test is performed, a specimen such as blood, saliva, or urine is taken from the test subject. An aliquot, or measured portion of that specimen, is then used to perform the actual testing. The aliquot portion serves as a representative sample of the specimen as a whole.
When do you use the term aliquot in chemistry?
Answer Wiki. The term ‘aliquot’ is usually used when the fractional part is an exact divisor of the whole; the term ‘aliquant’ has been used when the fractional part is not an exact divisor of the whole (e.g. a 15 mL portion is an aliquant of 100 mL). When a laboratory sample or test sample is ‘aliquoted’ or otherwise subdivided,…
What makes 5ml of NaCl an aliquot sample?
The 5ml samples would be our aliquots as they are the part to the whole, or 25ml total NaCl solution. Given what we have learned about part to whole, why do you suppose those two glasses of lemonade can be classified as aliquot samples?
How is the volume of a drug Measured?
Then, an aliquot of the solution containing the desired amount of drug is removed. Both the total volume of solution and the aliquot volume should be such that they are easily and accurately measured (preferably whole number multiples of 5 ml).
Which is the second function of an aliquot?
A second function of aliquots is associated with chemical titrations. Titrations are a useful technique that helps you determine the concentration of unknown solutions from known solutions. The most common use of titration is to determine how acidic or basic an unknown solution is.
