UV-Visible Spectrophotometer 190–1100 nm 1.0 nm ATOMFAIR®

The UV-visible spectrophotometer contains a deuterium lamp that emits harmful UV radiation; always operate with the sample compartment closed to prevent exposure. The instrument requires a stable electrical supply (110/220 V, 50/60 Hz) and should be placed in a clean, dust-free environment to maintain optical performance.

• UV Radiation Safety: The deuterium lamp emits UV radiation that can cause eye and skin damage; never operate the instrument with the sample compartment open.
• Electrical Safety: Ensure the instrument is connected to a grounded outlet and that the power cord is not damaged to avoid electric shock.
• Environmental Conditions: Operate the spectrophotometer in a temperature-stable, low-humidity environment to prevent condensation and drift.

Follow these steps to safely initialize and perform a measurement. Proper warm-up and baseline correction are essential for accurate results.

Required Equipment: SpectraCore UV 3101 spectrophotometer, 4-position cell holder, Cuvettes suitable for UV-Vis, Reference blank solution

1. Inspect Instrument
   Inspect the sample compartment and ensure it is clean and free of debris.
2. Power On
   Connect the power cord and turn on the main power switch, then allow the lamps to warm up for the recommended stabilization period.
3. Set Parameters
   Set the desired wavelength, scanning speed, and measurement mode using the touch screen interface.
4. Prepare Samples
   Place the blank solution and sample solutions into clean cuvettes and insert them into the cell holder.
5. Perform Measurement
   Initiate the baseline correction with the blank, then measure the absorbance or transmittance of the samples.
6. Turn Off
   After measurement, turn off the instrument and cover the sample compartment to protect the optics from dust.

Double-beam UV-Vis spectrophotometer with 1.0 nm bandwidth and 190-1100 nm range, providing high wavelength accuracy (±0.1 nm at 656.1 nm) and low stray light (≤0.03%T) for reliable quantitative analysis. The fixed bandwidth and standard 10 mm cell holder define its application envelope.

Positive

• Double-beam optical system with dual lamps: Double-beam design with tungsten and deuterium lamps ensures stable baseline compensation and accurate measurements across the full UV-Vis range (190-1100 nm).
• High wavelength accuracy and low stray light: Wavelength accuracy of ±0.1 nm at 656.1 nm and stray light ≤0.03%T at 220/360 nm support reliable quantitative analysis in demanding UV applications.

Trade-offs

• Fixed 1.0 nm bandwidth limits resolution: The fixed bandwidth of 1.0 nm may restrict spectral resolution for applications requiring finer slit widths, such as resolving narrow absorption peaks or high-precision derivative spectroscopy.
• Standard 10 mm cell holder restricts path length: The included 4-position cell holder accepts only 10 mm cuvettes; measurements requiring non-standard path lengths (e.g., 1 mm or 50 mm) require optional long-cell holder, adding procurement lead time and cost.
