A densitometer is a tool used to gauge the degree of blackness (or optical density) in a reflective surface, semi transparent material, or photographic material.
Essentially, a light source directed at a photoelectric cell constitutes a densitometer.By comparing the readings, it can calculate the density of a sample that has been placed between the light source and the photoelectric cell.The same parts are still used in modern densitometers, but they also have electronic integrated circuitry for improved reading.
Densitometric analysis of the chromatogram is feasible without derivatization if a separated material absorbs UV or white light or can be excited to fluoresce.
A densitometer, also known as a scanner, measures the light that is reflected or emitted when a narrow beam of light with a single wavelength is moved across a TLC plate in order to assess its tracks.
Light is transformed into an electrical indication by a photomultiplier, which then displays the analog chromatogram curve as a function of migration distance. The highest height and/or area can be quantitated after the raw data has been integrated. A very precise measurement is densitometry.
Usually, less than 100 ng of material can be found in each zone. The measurement limit for some substances, like aflatoxins, is in the picogram range.
The Global Densitometer market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The TBX 1000 Transmission Densitometer from Tobias Associates measures ocular diffuse optical density (OD) to 6.00D. This broad measuring range enables the evaluation of a large variety of substrate, laminate, and film types.
The TBX 1500 and TBX 2000, both in the new range, also compute positive and negative dot areas and measure percent opacity and transmission.The TBX 1000 Series offers a very high level of precision and accuracy, as well as an optional color filter for specific uses.
It is extremely durable and requires little upkeep or repair. The TBX line of products, in its most recent iteration, is yet another illustration of the top-notch engineering for which Tobias is justly renowned.
