Question 6 Which of the following statement is INCORRECT? Gravimetry and titrimetry are classical method of analysis because measuring the mass and volume is the fundamental of all analytical measurements, thus those two are the oldest analytical technique. O Analytical Chemistry involves the application of techniques and methods to obtain and assess qualitative, quantitative, and structural information on the nature of matter. O Quantitative reveals the identity of the elements and compounds in a sample while qualitative analysis analysis indicates the amount of constituent present in a sample. O Analytical Chemistry deals with methods for determining the chemical composition of samples of matter. It is a measurement science consisting of a set of powerful ideas and methods that are useful in all fields of science and medicin

A young researcher was evaluating a standard method for determining the methylmercury content in blue fin tuna using high performance liquid chromatography (HPLC). She determined the standard deviation (?)(s) for the method to be 0.440.44 ppb and assumed that ?s was a good approximation of ?σ . As a test, she used this method to evaluate the methylmercury content in a National Institutes of Standards and Technology (NIST) standard and determined the unknown amount to be within 0.210.21 ppb (?)(μ) of the known mean with 99% probability. How many replicate measurements of the NIST standard did the researcher perform?

You are developing a Ca detection method for a graphite furnace AA instrument. Your analysis of ten blank samples gives a standard deviation of 0.265 ppb. To establish your limit of detection (LOD), what concentration of Ca should be spiked into your blanks?
Internal standard (As , Cs ), analyte with known concentration (Ax , Cx ) In a chromatographic equipment, a solution containing 0.006727 X and 0.008331 M S give peak area of Ax= 2316 and As= 207. To analyze an unknown sample, 5.0mL of 0.008331M S was added to 5.0mL of X, and the mixture was diluted to 50.0mL. This mixture gave a chromatography spectrum with area Ax= 3206 and As= 200. Find Cx.
