Recommended Reagents for GC DerivatizationChemically Modify Your Sample to Improve the Chromatography!

When do you use derivatization?

When you need to:

1. Increase or decrease the volatility of the analytes to improve separation

2. Improve peak symmetry by reducing interaction of sample and column

3. Increase detector response (i.e. ECD)

4. Enhance thermal stability

What are the requirements for a good reagent?

It will:

1. Not cause any rearrangements or structural changes in the analyte

2. Produce a reaction that is 95- 100% complete

3. Produce a stable derivative

4. Not contribute to loss of sample during the reaction

5. Produce a derivative that is inert to the column and connections

6. Not produce interfering byproducts

Silylation replaces an active hydrogen atom (-OH, -NH2, -NHR, -SH) with a silyl group. Generally it reduces the polarity of the compound and decreases possibility of hydrogen bonding.

Need Ion Chromatography Standards?Alltech has the most complete selection of IC standards and the ability to manufacture custom standards. See pages 319-320.

combined with TMCS as a catalyst

CMDMCS• Longer retention times than TMCS derivatives• Enhanced ECD response

• May be used directly on HCl salts of compounds

MTBSTFA [N-(tert-butyldimethylsilyl)-N-methyltrifluoroacetamide]

• Derivatives more stable than common TMS derivatives• Produces a distinct M-57 ion in GC/MS analysis• Even more effective when combined with TBDMCS as

a catalyst

TMCS (Trimethylchlorosilane)

• Similar to HMDS when used alone• Very effective as a catalyst to other reagents

MSHFBA (N-Methyl-N-trimethylsilylheptafluorobutyramide)

Alkylation (Esterification) ReagentsAlkylation replaces an acidic hydrogen (carboxylic acids, phenols) with an alkyl group. Alkyl esters are extremely

stable and can be stored for long periods of time.

BF3/Methanol (14%)• Convenient and inexpensive method for forming

esters• Reagent is stable for six months if refrigerated and

kept dry

Transesterification Reagents

BCl3/Methanol (10%)• More stable than 14% BF3/Methanol– may be stored

for several months at room temperature

BF3/n-Propanol (14%)• n-Propyl esters for short chain mono- and dicarboxylic

acids• Retention times longer than methyl esters

BF3/n-Butanol (14%)• n-Butyl esters for short chain mono- and dicarboxylic

acids• Retention times longer than methyl esters

Meth-Prep™ I• On-column derivatization• Aqueous solution does not give solvent peak

Instant Methanolic HCl Reagent Kit• Acid catalyzed esterification of alcohols• Reagent is generated before use and is stable for one

week at room temperature

Transesterification is the process of converting one type of ester into another. Most commonly this is a very large ester (i.e. triglycerides, steryl esters, wax esters, phospholipids) converted into a methyl ester that is more easily analyzed.

Meth-Prep™ II• In one step forms fatty acid methyl esters from

triglycerides at room temperature• Requires no extraction before injecting into GC• Faster than sodium methoxide reagents

Sap Ester Reagent Kit• Useful for converting lipids to fatty acid methyl esters• Reagent prepared fresh before using

Sodium Methoxide/Methanol• Converts a wide range of large esters to fatty acid

methyl esters

Improving Peak Shape in GCMany drugs are reactive in a GC column. This can lead to tailing or low response. To improve the chromatography, many choose to make a derivative of the material to increase its stability and improve the peak shape. The most commonly used reagent is MSTFA. It is co-injected with the sample and forms the derivative in the GC injector. See the Reagents Section for more information.

Do you want to improve your drug recoveries?Alltech’s Drug-Clean mixed mode silica-base SPE packing combines reversed-phase and ion exchange functionalities in a single column. This allows high drug recoveries with minimal impurities compared to single-phase extractions.See pages 6-7 for more details or request Product Support Sheet #M102

Need help getting rid of all of those drug sample vials?Safely separate the solutions from the vials using the Alltech Vial Crusher. See page 122 for more info.

Complete line of drug standards including pure materials and pre-weighed ready-to-dilute materials are available. For complete listing, request Bulletin 469.
