Product Description

The Variable Pathlength Liquid Spectrophotometer Cell can eliminate the need for a large collection of different fixed pathlength cells at an economical price.
The Variable Pathlength Liquid Spectrophotometer Cell consists of a cylindrical stainless steel chamber containing parallel windows. The pathlength may be continuously adjusted from 0.05mm to 5mm and reproduced within 0.001mm (1 micrometer). A vernier scale provided on the cylinder permits the cell pathlength to be read within 0.0005mm (0.5 micrometer).
In order for weaker absorption bands of many liquids to appear with the proper intensity, the stronger bands will be totally absorbed and their exact location thus obscured. In these situations, the Variable Pathlength Cell may be precisely adjusted to provide just the right intensity for exact location of both weak and strong bands.
The Variable Pathlength Liquid Spectrophotometer Cell is useful in both solvent compensation and differential analysis. When filled with solvent and mounted in the reference beam of a dispersive spectrophotometer, its pathlength may be adjusted to compensate for unwanted solvent absorption in the sample beam.
In differential analysis, two liquids are examined that may differ only slightly in the concentration of a minor component. Careful adjustment of the variable cell pathlengths will tend to enhance the spectrum of the minor component contained in a fixed path cell in the sample beam.

Its manual control and passive operation ensure ease of use and low maintenance, while factory calibration guarantees dependable accuracy.

FAQs of Infrared Variable Pathlength Spectrophotometer Cell:

Q: How does the pathlength adjustment mechanism work in this IR spectrophotometer cell?

A: The pathlength can be continuously set from 0.01 mm to 10 mm using the micrometer screw integrated into the cell body. Turning the screw moves internal components to adjust the liquid sample chambers thickness, allowing for precise spectral measurements.

Q: What types of spectrophotometers is this cell compatible with?

A: This cell is designed to fit standard IR spectrophotometer mounts, ensuring compatibility with most commonly used infrared spectrophotometer models in laboratory environments.

Q: When should I consider recalibrating the cell, and is certification available?

A: Recalibration is generally not required unless the cell is repaired or window materials are replaced. Factory calibration with certification is available on request, offering traceable accuracy for regulated laboratories or demanding applications.

Q: Where can this spectrophotometer cell be used regarding temperature and pressure conditions?

A: The cell is rated for use at ambient temperatures up to 250C and is safe under pressures up to 2 bar, provided suitable seals are employed and compatible window materials are selected for these conditions.

Q: What is the process for preparing the cell for a measurement?

A: To prepare, mount the cell in your spectrophotometer, use the micrometer screw to set the desired pathlength, fill the cell with your liquid sample, and ensure all seals and windows are properly installed and tightened for accurate and leak-free measurements.

Q: How do different window materials benefit various analyses?

A: Window materialsKBr, ZnSe, CaF2, and borosilicate glassoffer different transmission ranges and chemical durability. Selection depends on the spectral region of interest and compatibility with your sample, ensuring optimal performance and long-term reliability.
