Top 10 Questions for Assayer Interview

1. What are the different techniques used in assaying?

There are various techniques used in assaying, including:

• Gravimetric analysis: Determining the amount of a substance by weighing it after it has been precipitated or volatilized.
• Volumetric analysis: Determining the concentration of a solution by reacting it with a known volume of another solution of known concentration.
• Spectrophotometry: Measuring the absorption or emission of light by a sample to determine its concentration.
• Atomic absorption spectroscopy: Measuring the absorption of light by atoms in a sample to determine their concentration.
• Inductively coupled plasma mass spectrometry: Measuring the mass-to-charge ratio of ions in a sample to determine their elemental composition.

2. What are the different types of samples that can be assayed?

Ores and minerals

• Assays are performed on ores and minerals to determine their metal content.
• This information is used to determine the value of the ore or mineral and to plan for its extraction and processing.

Environmental samples

• Assays are performed on environmental samples to determine the presence and concentration of pollutants.
• This information is used to assess the environmental impact of human activities and to develop strategies to reduce pollution.

Food and agricultural products

• Assays are performed on food and agricultural products to determine their nutritional content and to ensure their safety.
• This information is used to develop healthy and nutritious food products and to prevent the spread of foodborne illnesses.

3. What are the quality control procedures that are used in assaying?

There are a number of quality control procedures that are used in assaying, including:

• Blanks: Samples that do not contain the analyte of interest are analyzed to check for contamination.
• Standards: Samples with known concentrations of the analyte of interest are analyzed to calibrate the equipment and to ensure accuracy.
• Replicates: Multiple samples are analyzed to check for precision.
• Control charts: Data from quality control samples is plotted on control charts to monitor the performance of the assay over time.
