How can one determine the appropriate solvent system for TLC?
To determine the appropriate solvent system for TLC (thin layer chromatography), one can consider the polarity of the compound being analyzed and choose a solvent system with a polarity that allows for good separation of the compounds on the TLC plate. Testing different solvent systems with varying polarities can help identify the most suitable one for the specific compounds being analyzed.
How long is serum viable for alcohol testing?
Serum is typically viable for alcohol testing for up to 3-5 days when stored in a proper container at the recommended temperature. However, it is always best to consult with a medical professional or testing facility for specific guidance on the viability of serum samples for alcohol testing.

What is a good science fair experiment on permanent marker remover?
A good science fair experiment on permanent marker remover could be testing the effectiveness of different household products (such as vinegar, baking soda, rubbing alcohol) in removing permanent marker stains on different surfaces (like paper, fabric, and plastic). This experiment would involve applying the marker on each surface, letting it dry, then testing various removers to see which one works best based on the time and effort needed to remove the marker.
Why is alcohol used when testing to see if chlorophyll is needed for photosynthesis?
Chlorophyll dissolves (becomes mobilized) in alcohol. Once mobilized, it can be separated from the other pigments by chromatography.
What are two industries that use chromatography?
Two industries that use chromatography are pharmaceuticals and environmental testing. In pharmaceuticals, chromatography is used for drug development and quality control. In environmental testing, chromatography helps analyze pollutants in air, water, and soil.

How is chromatography used in drug testing?
Chemists use liquid chromatography a complex of substances. They can use chromatography to analyze drugs and also test blood and urine samples. People use it to separate and purify different substances and chromatography can detect the presence of drugs in a person's blood.
How do they give alcohol test?
by breathing into an alcohol testing unit or blood analysis

What is the purpose of the alcohol in testing a leaf for starch?
It is to remove the chloroplast and dissolve in the alcohol and turn it green.
Incidental alcohol exposure and ETG testing?
Incidental alcohol exposure (alcohol in hand sanitizer, alcohol in mouthwash, alcohol in medicines, etc.) can cause a false positive result for drinking alcohol.

Does tasc in tucson az use etg testing for alcohol?
Yes, TASC (Treatment Accountability for Safer Communities) in Tucson, AZ, utilizes EtG (ethyl glucuronide) testing for alcohol. EtG testing is a sensitive method used to detect recent alcohol consumption, as it can identify alcohol metabolites in the body for up to several days after drinking. This type of testing is often employed in programs aimed at monitoring sobriety and compliance with treatment plans.
