AB SCIEX SelexION™ Technology

Keystone Bioanalytical is the first CRO to utilize AB SCIEX SelexION™ Technology, an effective differential ion mobility spectrometry tool for improving data quality in the quantitation & characterization of challenging samples requiring advanced analytical selectivity.


The AB SCIEX QTRAP® 6500 LC/MS/MS merges triple quadrupole and linear ion trap capabilities with revolutionary new multi-component IonDrive™ technology to produces the world's most sensitive and selective triple quadrupole. The AB SCIEX 6500 offers up to 10X greater sensitivity and a 20X increase in detector dynamic range - with no compromise in mass range.


The AB SCIEX QTRAP® 5500 LC/MS/MS system is the next-generation technology which is designed to excel at metabolite identification, detection and confirmation of low-level pesticides, and protein/peptide quantitation for biomarker verification and validation. Redesigned from the ground up using our new, fast eQ™ electronics, but bred from our industry standard triple quadrupole line of mass spectrometers, the QTRAP® 5500 system brings in a new era of performance.

LUMINEX MAGPIX® multiplexing system

MAGPIX is a versatile multiplexing platform capable of performing qualitative and quantitative analysis of proteins and nucleic acids in a variety of sample matrices. This affordable system can perform up to 50 tests in a single reaction volume, greatly reducing sample input, reagents and labor while improving productivity.
