The Raman effect, also known as Raman scattering, was discovered back in 1928 by CV Raman. The Indian physicist observed that when light traverses an object, a small part of that light changes frequency. By small, we really mean tiny – only about 1 part in 100,000 is affected by this. However, this tiny amount of scattered light can reveal a great deal. When the light changes frequency, it creates a specific pattern depending on the molecular makeup of the substance it hits. CV Raman went on to win a Nobel prize for his observations.
Because only a tiny fraction of the light changes frequency, the more intense the initial light source the better the analysis. For this reason, the power of the Raman effect was not properly adopted on a widespread basis until after the invention of the laser in the 1960s. The first Raman spectrometers were big and cumbersome – a far cry from the portable devices we know today!
Nowadays, handheld Raman spectrometers can fit lab quality analysis into the palm of your hand. Progeny by Rigaku is one of the most technologically advanced spectrometers on the market today. But what makes it so different from other handheld Raman spectrometers?
Progeny Uses 1064nm Laser Excitation
The Progeny’s 1064nm laser excitation minimises moisture and sample induced fluorescent interference. The 30-490 mW laser power can also be adjusted in 5mW increments for optimum analysis. This, combined with its comprehensive on-board library, means that you receive full and accurate analysis of a vast range of substances. We’re talking powders, liquids, solids, polysorbates, cell cultures and much more.
Safe and Speedy Results – Even Through Containers
The Progeny handheld Raman analyser can effectively analyse materials in seconds, offering a simple to read Pass/Fail result. Even better than that, it can analyse the contents of a container without needing the container to be opened. This means that there is less of a risk that your sample will be contaminated and that there is no danger posed to the operating personnel.
Ease of Use
The Progeny handheld Raman analyser is truly easy to use. Not only does its ergonomic design fit snugly in your hand, but its technical capabilities means that you have everything you need to hand. Some of its technical features include;
- WiFi/USB connectivity
- Touchscreen (inspired by your smartphone!)
- E-signature – meaning that you can review, approve, reject and sign electronically with full 21 CFR Part 11 compliance
The full functionality and power of the Progeny handheld Raman spectrometer really should be seen to be believed. We are offering free demonstrations of the Progeny analyser across on our sister site, Antech.ie. You can book yours by following this link!
