Why are samples initially hydrolysed with nitric acid before the molybdate test is carried out?
Samples are initially hydrolyzed with nitric acid to convert complex organic and inorganic compounds into simpler forms, ensuring that all relevant phosphorus species are released in a soluble form. This step helps to prevent interference during the molybdate test, which detects phosphates. By breaking down the sample, nitric acid enhances the accuracy and reliability of the subsequent measurement of phosphate concentration.

Which type of samples analysed by hplc?
High-performance liquid chromatography (HPLC) is commonly used to analyze a wide range of samples, including pharmaceuticals, food and beverages, environmental samples, and biological samples such as proteins, amino acids, and nucleic acids.
How blood inorganic phosphate estimated?
Blood inorganic phosphate levels can be estimated using a colorimetric assay, where phosphate ions react with molybdate to form a colored complex. This complex is then measured spectrophotometrically at a specific wavelength, allowing for the quantification of inorganic phosphate in the sample. Blood samples are typically collected in heparinized tubes to prevent clotting, and the assay can be performed on serum or plasma. The results are usually expressed in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L).
What is the correct sequence when obtaining multiple samples of blood?
The correct sequence when obtaining multiple samples of blood is to collect samples in the following order: blood cultures, non-additive tubes (for serum), tubes with additives (e.g., EDTA, heparin, citrate), and finally, blood samples for coagulation studies. This sequence ensures that samples are not contaminated by additives from other tubes and prevents cross-contamination.
What is the difference between control samples and test experimental samples?

Should the density of Al be the same for all Al samples?

What is molybdate test?
molybdate test is a test to detect the presence of phosphate at your solution and the appearance at the lab is purple pink as the phosphate is containing lipids and lipids will react with molybdate test to give pink color. Hope this answer you
Why Ammonium molybdate is used in test for phosphorus?
Ammonium molybdate is used in the test for phosphorus because it forms a yellow complex with phosphorus, which allows for the colorimetric determination of phosphorus levels. This reaction is commonly used in spectrophotometric methods to quantify phosphorus in various samples.
