Core Principles of FTIR Technology!


Core Principles of FTIR Technology!

»   Basic Concept of Fourier Transform Infrared Spectroscopy

Fourier Transform Infrared Spectroscopy, or FTIR, is a smart way to study gases. FTIR uses a nifty gadget called a Michelson interferometer. Beams of light bounce and mix in the interferometer.

Next, a computer turns these light patterns into graphs. These graphs show what gases are present and in what amounts. This magic is possible thanks to the Fourier transform. FTIR can spot many gases in a snap and even find ones hiding in tiny amounts.

»   Benefits of Utilizing FTIR in Gas Analysis

• High Sensitivity

FTIR finds gases in tiny amounts. Even if there’s less than a pinch, like 0.5 ppm, FTIR can still spot it. That’s sharp!

• Broadband Analysis

FTIR can look at lots of gases all at once. Imagine peeking at SO2, NOX, CH4, and more, in a single glance. That’s handy.

• Rapid Scanning

Time matters. FTIR works fast. In less than 2 minutes, your data is ready. Like a race car, it zooms through tests.

• Quantitative Measurements

Numbers are important. FTIR tells you exactly how much of each gas is there. No guesswork. Pure facts.

• Low Noise

No need for earplugs. FTIR is quiet as a mouse with a signal-to-noise ratio greater than 15,000:1. Clarity wins.

• Multiplex Advantage

FTIR is like an octopus, doing many things at once. Studying several gases? FTIR has it covered.

• Reduced Sample Size

FTIR doesn’t hog. With just a small bit of gas, like a thimble, FTIR can do a full check-up.

• Real-time Monitoring

Watch FTIR work live. As gases change, FTIR shows you right away. Always in the know.

• Enhanced Resolution

FTIR is sharp, like an eagle eye. It splits details into bits as tiny as 4 cm-1. Nothing slips by.

• Gas Fingerprinting

Each gas has a special mark. Like a detective, FTIR spots these marks. That’s how it tells gases apart.

• Non-destructive Analysis

FTIR is gentle. No breaking or tearing. Your sample stays just like it was.

• Chemical Identification

Meet a mystery gas? FTIR is on the case. With built-in data on many gases, FTIR solves the riddle.

• Portable Systems

Take FTIR anywhere. With a handy size, 395mm170mm345mm, it’s ready to travel. Plus, it’s lighter than three bricks.

• Customization Flexibility

Need something special? FTIR adjusts. Set the range, gases, and more. FTIR makes it just right.
