Fast sample preparation


This Chromsystems reagent kit is designed for the specific determination of the antiepileptic drugs ethosuximide, zonisamide, primidone, phenobarbital, phenytoin, carbamazepine, lamotrigine, trileptal® (oxcarbazepine, syn. oxcarbamazepine) and sultiame in serum or plasma. In addition, the analogues carbamazepine-10,11-epoxide, 10,11-dihydro-10,11-dihydroxycarbamazepine, 10-OH-carbamazepine and 2-ethyl-2-phenylmalondiamide (PEMA) can be analysed.
Sample preparation is based on a simple but efficient precipitation step. To separate and quantify all analytes a chromatography with high resolution is used.


Technical Data

Method of Analysis


Number of Tests



10-OH-carbamazepine, Carbamazepine, Carbamazepine-10,11-epoxide, Ethosuximide, Lamotrigine, Oxcarbamazepine (Trileptal®), Phenobarbital, Phenytoin, Primidone, Sultiame, Zonisamide

Analysis Time

High Resolution: 22 min


A precolumn has to be used.



Sample Preparation

  • Pipette 100 μl serum/plasma (standards, controls, research specimens) and 150 μl Internal Standard into a labelled reaction vial, mix briefly (vortex).
  • Add 50 μl Precipitation Reagent, mix 1 min (vortex).
  • Centrifuge 10–15 min at 9000 x g.
  • Mix 100 μl of the supernatant with 100 μl Stabilisation Buffer.
  • Inject 20 μl into the HPLC system.

Sample Stability

The research samples can be kept refrigerated (+2 to +8°C) for approx. one week. For longer storage (up to 2 weeks) deep-freeze them below –18°C.

Additional Info

Analysis of antiepileptic drugs requires a simple isocratic HPLC system with HPLC pump, injector and UV detector. The use of a thermostat-controlled column oven avoids temperature variations and optimises the stability of the separation.
