What is baseline in uv?
In UV spectroscopy, the baseline refers to the horizontal line at zero absorbance on the absorbance axis. It represents the reference point for measuring the absorbance of the sample. The baseline should be stable and noise-free to ensure accurate measurement of the absorbance of the sample.
How do you get a good FT-IR baseline?
To get a good FT-IR baseline, ensure that the instrument is properly calibrated, the sample chamber is clean, and measurement conditions are consistent. Use a blank solvent or reference material to correct for any background noise, and average multiple scans to improve signal-to-noise ratio.
Difference between spectrophotometry and differential spectrophotometry?
Differential spectrophotometry is a spectrophotometric analytical technique in which a solution of the sample's major component is placed in the reference cell and the recorded spectrum represents the difference between the sample cell and the reference cell...basically it uses major component of system as reference and NOT solvent ..for example if a enzyme ligand system is to be assayed ..enzyme + solvent is reference and enzyme + ligand + solvent is test sample..its for quantitative detection.
What is propelling force in paper chromatography?
The propelling force in paper chromatography is capillary action, where the solvent moves through the paper due to the attraction between the solvent and the paper fibers. This causes the components in the sample to separate as they are carried at different rates along the paper.
What is the moving solvent called in chromatography?
The moving solvent in chromatography is referred to as the mobile phase. It carries the sample through the stationary phase, allowing for separation based on differences in affinity between the components of the sample.
Why is it important to do a background scan before running the sample in IR?
Conducting a background scan before running a sample in infrared (IR) spectroscopy is crucial to establish a baseline for the measurement. This baseline helps identify any noise or interference from the solvent, sample holder, or the instrument itself, ensuring that the resulting spectra are accurate and reliable. By subtracting the background from the sample spectrum, researchers can isolate the specific absorption features of the sample, leading to more precise analysis and interpretation of the data.
Can a sample be analysed on filter paper in the electron microscope?
No you can't. what an idiot

What should you do if your water line tastes like salt?
Take a sample to a lab to get analysed.

Fix the PH and Radium in your well water?
Get a sample analysed at a lab FIRST -so you know what to do .
Does your bearded dragon have worms?
Only way to find out - is to take a stool sample to a vet and have it analysed.
What is a measure of how clear water is in a water system?
This is 'turbidity' and is measured in 'ppm' when you have a water sample analysed in a lab.
Who do you call for well water problems?
You call a well or filtration company . First get a sample analysed at a lab.
Explain why the sample to be seen through a microscope cant be thick?
the light from the lamp below the table would not get through the sample, meaning it could not be seen or analysed.
How can you remove brown coloring of well water?
You get a sample analysed then use appropriate filters for whatever is making it brown.
