Rt-ßDEXm

(permethylated ß cyclodextrin doped into 14% cyanopropylphenyl/86% dimethyl polysiloxane e)

By adding ß or y cyclodextrin to our bonded Rtx®-1701 stationary phase, we greatly enhance overall utility and column lifetime for the chiral columns, compared to columns that have pure cyclodextrin stationary phases. Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and our columns continue to demonstrate stability after hundreds of temperature program cycles. Refer to the applications section of this catalog for examples, or call our Technical Service chemists for assistance in matching a column to your chiral analysis.

Applications

• General purpose chiral phase with many published applications.
• Terpenes
• Alcohols

Micro Extraction by Packed Sorbent (MEPS)

Micro Extraction by Packed Sorbent (MEPS) is a new development in the field of sample preparation by Solid Phase Extraction (SPE). MEPS performs the same function as SPE, but with some significant differencies:

• MEPS works with much smaller sample amount (as small as 10µL) than full scale SPE
• MEPS can be fully automated – the sample processing, extraction and injection steps are performed on-line using the same syringe
• MEPS is applicable to GC and LC
• Significantly reduces the volume of solvents and sample needed

The MEPS product consists of two parts, the MEPS Syringe and the MEPS Barrel Insert and Needle Assembly (BIN). The BIN contains the SPE phase, and is built into the syringe needle. The BIN is used with a 100µL or 250µL gas tight MEPS syringe that allows fluid handling at normal SPE pressures. When the BIN is exhausted, or another phase is required, the BIN is easily exchanged by simply unscrewing the locking nut and removing/replacing the BIN.
