Analytical techniques

3. determines the identity of the sample
5. a graph showing the information from a mass spectrometer with the mass of each particle and the relative abundance
8. a technique used to determine the molecular or atomic composition of an element
9. where an atom absorbs additional energy
13. curve a graph of known values used to find an unknown value.
15. where the discrete frequencies of radiation emitted are analysed to provide qualitative and quantitative information about the sample
16. the distribution of frequencies of electromagnetic radiation emitted by an excited or heated atom.

1. a measurement of the amount of substance present in a sample
2. can affect a measurement in a random way
4. value the measurement of the relative amount of radiation that is absorbed by a sample.
6. when a substance is heated until it is a gas.
7. gives a consistent error
10. a measurement of the amount of substance present in a sample
11. to read or construct a new data point that has not been measured but is within the measured data range.
12. a particle representing a quantum of light
14. a filter used to ensure only radiation of a specific frequency is shone at a sample
