What is a Spectrophotometer?
A spectrophotometer is an advanced scientific instrument used to measure the amount of light absorbed by a sample at specific wavelengths. In the context of water analysis, spectrophotometers are crucial tools for assessing water quality by detecting and quantifying various contaminants, pollutants, and chemical substances present in water.
How Does the Spectrophotometer Work?
The light emitted by the light source falls through the entrance slit on the monochromator and is deflected by the grating situated towards the exit slit. This mechanism, enables the selected wavelength to be accurately reproduced.
The semi-transparent mirror deflects the reference beam while allowing the light beam to pass through to the sample in the cuvette. The photodiodes act as detectors and transmit these signals to the microprocessor. The result is calculated and issued as a value in the display. Spectrophotometer's working principle is based on Lambert-Beer’s Law—don’t worry, it’s simpler than it sounds! Let’s take a quick look at what it actually means.
Lambert Beer's Law:
Lambert-Beer’s Law—describes the relationship between the light absorption, path length, and the concentration of a substance in a solution. When light passes through a solution, some of it is absorbed depending on how much of the substance is present: the higher the concentration, the more light is absorbed. The formula is:
A=ε⋅c⋅l, Where:
A = absorbance (no units)
ε = molar absorptivity (L·mol⁻¹·cm⁻¹)
c = concentration (mol/L)
l = path length (cm)
This principle is essential in analytical instruments like photometers and spectrophotometers, ensuring accurate measurements across various fields.
Why Prefer a Spectrophotometer for Water Analysis?
For comprehensive, repeatable, and accurate water testing, spectrophotometers are an ideal choice. They are preferred for the following reasons:
- Broad Wavelength Range: Detects a wide spectrum of contaminants, from UV to visible light.
- High Sensitivity: Detects even low concentrations of pollutants, perfect for environmental and regulatory testing.
- Accurate, Repeatable Results: Delivers consistent data with minimal error.
- Ease of Use: User-friendly interface, suitable for both experts and beginners.

What is the difference between Vis and UV-Vis Spectrophotometers?
A Visible (Vis) spectrophotometer operates in the wavelength range of 320 to 1100 nm, while a UV-Visible (UV-Vis) spectrophotometer covers a broader range from 190 to 1100 nm. The UV-Vis spectrophotometer is generally preferred for specific analyses that require measurements in the ultraviolet range, such as determining nitrate concentrations in drinking water according to APHA Standard Methods and measuring ADMI color values in samples (when the values extend up to 1200 Pt-Co units).

FAQs – We Know What You’re Thinking! You Ask, We Answer!
How is a spectrophotometer different from a photometer?
The key difference between photometers and spectrophotometers lies in how they use light to measure the concentration of substances in a water sample. Both instruments work by measuring how much light is absorbed by the sample at specific wavelengths, as different substances absorb light uniquely across the spectrum.
Photometers measure light absorbance using interference filters at fixed wavelength, making them suitable for detecting specific concentration of parameters. Spectrophotometers, however, can scan across a wide range of wavelengths in the UV-Visible spectrum. This allows them to identify and wider range of concentration of parameters in a sample, providing more detailed analysis.
Do we need to zero the instrument with a blank sample or with air?
Different parameters require different methods, and each method has its own specific zeroing procedure. To ensure accuracy, refer to the Lovibond® Handbook of Methods, where the correct zeroing instructions are provided within each parameter.
I am using a spectrophotometer of another brand. Can the Lovibond® Handbook of Methods still be helpful?
Yes! Absolutely! Even if you're using a spectrophotometer from another brand, the Lovibond® Handbook of Methods can still be useful. It comprises perfect water testing methods and explains them in 10 different languages. Also, it describes each method in detail, with step-by-step pictorial instructions. The handbook also covers the basics of water analysis, provides references to relevant sources and norms, suitable reagents, and explanations of potential interferences. This handbook can become your go-to reference for reliable and accurate water testing.
Is a spectral bandwidth of 1 nm suitable for water testing?
While 1 nm provides extremely high precision, it is not necessary for water testing. Most water treatment applications don’t require this level of detail and can function effectively with the more than 1 nm spectral bandwidth.
In what cases should a spectral bandwidth of 1 nm be used for measurements?
The 1 nm measurement is ultra-precise and is required mainly in industries like life and biosciences.
