What is the basis of molecular sieve chromatography?
The purification in molecular sieve chromatography is dependent on the size of the molecules. The small molecules will enter into pores of gel while large molecules will be excluded from the pores.
Which chromatographic process would be least likely to be utilized in the crime lab?
Size-exclusion chromatography would be least likely to be utilized in the crime lab compared to other types such as gas chromatography or liquid chromatography. Size-exclusion chromatography separates molecules based on their size, making it less commonly used for the complex mixture analysis typically required in forensic investigations.
Separation of hemoglobin and riboflavin by gel chromatography?
The hemoglobin can pass through the gel first because it has a higher molecular weight, or larger molecule which could not pass through the pores of the beads in the gel, while the riboflavin would flow slower.
What are some ways chromatography can separate chemicals in a mixture?
Chromatography separates chemicals based on their affinity for a stationary phase and a mobile phase, allowing them to travel at different rates. Different types of chromatography like gas chromatography, liquid chromatography, and thin-layer chromatography utilize different mechanisms such as adsorption, partition, ion exchange, and size exclusion to separate the components in a mixture. By adjusting the conditions like solvent polarity, temperature, and column material, chromatography can effectively separate complex mixtures into individual components.
What can you use instead of chromatography paper in a paper chromatography test?
Instead of chromatography paper, you can use materials like coffee filters, filter paper, or even paper towels for paper chromatography tests. These alternative materials can absorb the solvent and help separate the components of a mixture based on their solubility and molecular properties, similar to chromatography paper.

What are disadvatages of chromatograph?
chromatography has many varieties -paper chromatography, sometime complexe mixtures cant be separated, TLC plates do not have long stationary phases -gaz chromatography: the molecule should be volatile -Chiral Chromatography can be expensive - Ion Exchange or Ion Chromatography: Turbidity should be low below 10ppm -Size Exclusion Chromatography: low resolution technique which gives few peaks and requires large differences in molecular weight for resolution -Gel chromatography: the target protein frequently becomes an abundant substrate for proteases that may also be present in the mixture. Another disadvantage is low sample handling.
How does a molecular sieve column function in the process of separating molecules based on their size and shape?
A molecular sieve column separates molecules based on their size and shape by trapping smaller molecules in the pores of the sieve material while allowing larger molecules to pass through. This process is known as size exclusion chromatography.

How can one identify compounds in gas chromatography?
Compounds in gas chromatography can be identified by comparing their retention times to known standards or using mass spectrometry to analyze their molecular structure.

What is the name of the method used to separate dyes?
Chromatography is the method used to separate dyes by allowing the components to move at different rates through a medium, such as paper or a column, based on their affinity for the medium and solvent. This technique separates the different dyes based on their molecular interactions with the moving phase.
What are other words you could use for chromatography?
Separation technique, analytical separation, molecular separation, chemical separation.
What type of chromatography would be used to separate two proteins?
Size exclusion chromatography would be ideal for separating two proteins based on their size. This technique separates proteins by allowing smaller proteins to enter the pores of the stationary phase while larger proteins elute first.
