22 Acylcarnitines and 13 Amino Acids in Solvent on Raptor HILIC-Si EXP Guard Column by LC-MS/MS
Internal standard peaks not shown.
|Column||Raptor HILIC-Si EXP guard column cartridge (cat.# 9310A0252)|
|Dimensions:||5 mm x 2.1 mm ID|
|Particle Size:||2.7 µm|
|Diluent:||85:15 Acetonitrile:water (v/v)|
|Inj. Vol.:||2 µL|
|A:||30 mM Ammonium formate in water|
|Notes||A 100 ng/mL standard mix of 22 acylcarnitines and 13 amino acids was prepared in 85:15 acetonitrile:water (v/v) which was fortified with known concentrations of stable isotope labeled internal standards. The solution was vortexed at 3000 rpm for 10 seconds to mix, and then the supernatant was injected for LC-MS/MS analysis using a Raptor HILIC-Si EXP guard column (no analytical column). The total cycle time was 1.2 minutes.|
