The HT300APlus is a proven liquid GC autosampler that also supports automated MEPS (Micro Extraction by Packed Sorbent)

Building upon the success of the popular and reliable HT300A liquid autosampler‚ the new HT300APlus offers you all the benefits of the standard HT300A with the addition of automated MEPS.

Microextraction by Packed Sorbent (MEPS):

MEPS is a new development in the field of sample preparation by SPE (solid phase extraction). It is the result of a collaboration between SGE‚ Mohamed Abdel-Rehim (AstraZeneca) and Lars G. Blomberg (University of Karlstead).

MEPS performs the same function as SPE, namely the purification of samples, but with some significant differences:
• MEPS works with much smaller samples than full scale SPE (as small as 10_l)
• MEPS can be fully automated, the sample processing‚ extraction and injection steps are performed on-line using the same syringe
• MEPS is applicable to both GC and LC
• MEPS significantly reduces the time needed to prepare and inject samples
• MEPS significantly reduces the volume of solvents and sample needed

MEPS syringe and Barrel Insert Needle (BIN) Assembly

Syringe and Barrel Insert Needle (BIN) Assembly:

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 100_l or 250_l gas tight MEPS syringe that allows fluid handling at normal SPE pressures. The BIN is easily changed when another phase is required or the current BIN is exhausted.


Further information on the benefits of MEPS is available in this white paper from SGE MEPS Application Notes:

• Generic MEPS PAH in Water Method • Large Volume Injection
• False Positive Drugs Tests
• Isolation of Phenols from Waste Water

MEPS Automation with the HT300APlus

The HT300APlus offers the perfect platform for automated MEPS. The ability to prepare and inject samples on-line using a single device reduces sample processing time and the need for operator intervention.

The HT300APlus works with all current MEPS syringes. There is no need to modify the syringe mount.
