Q & A

What is a spectrophotometer and how does it work?

A spectrophotometer is a laboratory instrument used to analyze compounds by measuring the absorption of light. It works by passing light through a sample and measuring the intensity of light that is absorbed or transmitted, allowing for qualitative and quantitative analysis.

What are the main components of a spectrophotometer?

The main components of a spectrophotometer include the sample compartment, light source (monochromatic), prism or filter, detector, and the controller/monitor for displaying results.

What are the different types of spectrophotometers mentioned in the script?

The script mentions four main types of spectrophotometers: visible spectrophotometers (VIS), ultraviolet (UV) spectrophotometers, UV-Vis (a combination of visible and UV), and infrared (IR) spectrophotometers, also known as FT-IR.

What is the function of a visible spectrophotometer?

A visible spectrophotometer uses visible light, which is part of the electromagnetic spectrum that can be seen by the human eye, to measure the absorption or transmission of light by a sample.

How does a UV-Vis spectrophotometer differ from a regular visible spectrophotometer?

A UV-Vis spectrophotometer combines both visible light and ultraviolet (UV) light, covering a broader range of wavelengths compared to a regular visible spectrophotometer, which only uses visible light.

What is the typical wavelength range for UV light used in spectrophotometers?

UV spectrophotometers typically use wavelengths ranging from 190 to 380 nanometers (nm), which fall outside the visible spectrum.

What is an FT-IR spectrophotometer used for?

An FT-IR (Fourier Transform Infrared) spectrophotometer is used to analyze absorption in the infrared region of the electromagnetic spectrum, typically to study molecular vibrations and chemical structures.

What is the significance of the 'double beam' design in the Return 3660 spectrophotometer?

The double beam design in the Return 3660 spectrophotometer allows for greater accuracy and stability by comparing the sample’s light absorption against a reference beam, minimizing errors and fluctuations in readings.

Why is the Return 3660 spectrophotometer recommended for laboratories?

The Return 3660 is recommended for laboratories due to its precision, versatility, and advanced features, making it suitable for a wide range of applications in academic, industrial, and research settings.

What services does PT Handaru Persada Mandiri provide for laboratory instruments?
