Leucine Enkephalin

Ensuring that your mass spectrometry instrumentation is tuned with the utmost precision is critical to producing precise and accurate results. Mass spectrometry operates on a minute scale making the smallest of calibration errors catastrophic to your results. Time and resources are frequently wasted correcting erroneous results caused by improperly adjusted parameters. This can easily be avoided by ensuring that your lab equipment is tuned precisely with the correct reference material. Leucine Enkephalin can help ensure that your instruments are fine tuned with the most precision possible.

Leucine Enkephalin is a lyophilized peptide intended to be used as a reference material for mass spectrometer tuning and calibration. This package contains two vials of 3 mg Leucine Enkephalin for a fantastic value. This package also contains two 3 mg ± 0.06 mg Leucine Enkephalin solid in a 12 mL, and an Amber Screw top Vial.

This product functions best when stored between - 20 degrees celsius and 10 degrees celsius upon arrival. Leucine Enkephalin boasts an impressive 6 months of shelf life after shipping and a 1 week shelf life upon reconstitution. Leucine Enkephalin is suited for uses in a variety of volumes including 2 ng/µL,1 ng/µL, 200 pg/µL, and 50 pg/µL. Leucine Enkephalin is optimally used with a mixture of half acetonitrile and half water with .1% formic acid. It is easy to transfer into mixtures using a 1,000 µL pipette for precision.

If you want to ensure proper calibration and tuning for an even wider set of conditions and methods you may want to check out our LCMS QC Reference Standard. The LCMS QC Reference Material is a 9 component mix of Acetaminophen, Caffeine, Sulfaguanidine, Sulfadimethoxine, Val,-Tyr-Val, Verapamil, Terfenadine, Leucine-Enkephalin and Reserpine packaged in a Waters vial. This standard provides a comprehensive reference for the use with LC/MS or MS instrumentation with a wide variety of conditions and methods.
