What is Weighing by difference?

Weighing by difference involves weighing a sample both before and after a process to determine the mass change due to the process. The difference in mass is the desired quantity being measured. This method is commonly used in analytical chemistry for accurate determination of constituents in a sample.


What are the sample problems in free falling bodies?

Some sample problems in free falling bodies include determining the time it takes for an object to fall a certain distance, calculating its final velocity upon impact with the ground, and finding the height from which an object was dropped based on its impact velocity. These problems typically involve using equations of motion like the kinematic equations to solve for various unknown quantities.


Which are method to determine magnetic susceptibility of Fecl3?

One method to determine the magnetic susceptibility of FeCl3 is by using a magnetic balance to measure the weight change of a sample before and after applying a magnetic field. Another method is by using a vibrating sample magnetometer to measure the magnetization of the sample as a function of an applied magnetic field. Finally, one can also use SQUID (Superconducting Quantum Interference Device) magnetometry to determine the magnetic susceptibility of FeCl3 accurately at low temperatures.


What is the difference between calibration sensitivity and analytical sensitivity?

Calibration sensitivity refers to the ability of an instrument to accurately detect changes in levels of a sample. Analytical sensitivity refers to the lowest amount of analyte that can be reliably measured by an assay. Calibration sensitivity is related to instrument performance, while analytical sensitivity is specifically related to the assay's detection limit.


What is XRD pole figure?

An XRD pole figure is a graphical representation of the orientation distribution of crystallites in a sample based on X-ray diffraction data. It provides information on the preferred orientation or texture of the crystalline material, showing how the crystals are aligned in different directions within the sample. Pole figures are useful for understanding the crystallographic orientation relationships and anisotropic properties of materials.

What condition should use the standard addition method?

The standard addition method is typically used in analytical chemistry when analyzing samples with unknown concentrations, where a known amount of standard solution is added to the sample to create a series of solutions with different concentrations. This method is particularly useful when the matrix of the sample interferes with other quantitative methods.


What is gravimitre precipitation method?

Gravimetric precipitation method is a technique used to determine the concentration of a substance in a sample by precipitating the substance and then measuring its mass. This method is commonly used in analytical chemistry for quantifying the amount of a specific element or compound in a solution.


What is a multiresidue method?

A multiresidue method is an analytical technique used to detect and quantify multiple pesticide residues or contaminants in a single sample simultaneously. This method improves efficiency by allowing for the analysis of different residues in one test, making it a valuable tool for food safety and environmental monitoring.

Why sample need to be diluted?

Samples sometimes need to be diluted to bring their concentration within the range of the measurement method, to prevent interference or saturation of the detector, or to ensure that the sample is compatible with the analytical equipment being used. Dilution can also help reduce matrix effects and improve the accuracy of the analysis.


What is western blot used for?

Western blot is used to detect any specific protein found in a sample. Normally tissue or cell lysates contain tons of different kind of proteins. By doing this analytical method one can identify the specific protein from the crude sample by antibodies.


What is assay on a dry basis?

An assay on a dry basis refers to expressing the concentration of a substance in a sample after removing the moisture content. This method is commonly used in analytical chemistry to provide a more accurate representation of the actual substance content in a sample by eliminating the variability introduced by water content.


What are used to organize and neatly display data?

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.


What is the branch of chemistry which study the composition of a sample?

This branch of chemistry is called analytical chemistry.


What is gross sample in analytical procedure?

A gross sample in an analytical procedure is a large, random sample that is collected from a bulk material or substance. It is representative of the entire lot and is used for further analysis and testing to ensure accurate results. Subsamples are typically taken from the gross sample for more detailed analysis in the laboratory.
