What is the difference between single and double beam spectrophotometer?
What is the difference between single and double beam spectrophotometer?
A single beam spectrophotometer has only one beam of light, while a double beam spectrophotometer has two beams of light, one passing through a reference solution and one passing through the sample.
What is split beam spectrophotometer?
A split beam spectrophotometer contains a beam splitter which channels light along a reference path and a sample path simultaneously to two separate detectors. Once submitted, we will try and place you in contact with a suitable Split-Beam Spectrophotometers supplier within 48 hours.
Why is dual beam preferred over single beam in spectrophotometry?
Double beam spectrophotometers operate faster and provide more reproducible results because they perform an automatic correction for the loss of light intensity as the beam passes through the sample and reference solution.
What is the purpose of using a double beam arrangement?
Unlike single-beam systems, double-beam systems determine measurement values using the ratio of sample beam intensity to reference beam intensity during both sample measurement blank correction. As shown, fluctuations in the light intensity do not affect measurement results.
