Key Concepts and Principles

Laws of spectroscopy

Spectroscopy is the study of the interaction between matter and electromagnetic radiation. There are two main laws of spectroscopy:

1. Absorption

Absorption spectroscopy involves the measurement of the absorption of light by a substance. It is based on the principle that different substances absorb light at different wavelengths. The key concepts related to absorption spectroscopy are:

• Definition and explanation
• Beer-Lambert Law
• Calculation of absorbance

1. Emission

Emission spectroscopy involves the measurement of the emission of light by a substance. It is based on the principle that when a substance is excited, it emits light at specific wavelengths. The key concepts related to emission spectroscopy are:

• Definition and explanation
• Fluorescence and phosphorescence
• Excitation and emission spectra

1. Fluorescence spectroscopy

Fluorescence spectroscopy is a type of emission spectroscopy that specifically focuses on the measurement of fluorescence. Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. The key concepts related to fluorescence spectroscopy are:

• Definition and explanation
• Fluorescence excitation and emission
• Applications in clinical laboratory instruments

Step-by-step Walkthrough of Typical Problems and Solutions

Calibration of Colorimeter and Spectro photometer is an essential step to ensure accurate and reliable measurements. The following steps outline the calibration process:

1. Preparation of standard solutions

To calibrate the Colorimeter or Spectro photometer, a series of standard solutions with known concentrations of the substance of interest are prepared. These solutions cover a range of concentrations.

1. Measurement of absorbance or fluorescence intensity

The standard solutions are then measured using the Colorimeter or Spectro photometer. The instrument measures the absorbance or fluorescence intensity of each solution.

1. Plotting calibration curve

The measured absorbance or fluorescence intensity values are plotted against the known concentrations of the standard solutions. This creates a calibration curve.

1. Determination of unknown concentrations

Once the calibration curve is established, unknown samples can be measured using the Colorimeter or Spectro photometer. By comparing the absorbance or fluorescence intensity of the unknown samples to the calibration curve, their concentrations can be determined.

Real-world Applications and Examples

Colorimeter and Spectro photometer have a wide range of applications in clinical laboratory settings. Some examples include:

Measurement of biochemical parameters
