Spectral Service AG developed the phospholipid analysis method using 31P-NMR spectroscopy over 30 years ago and we have established as global leaders in this field. Our team performs this analysis daily, handling around 50 samples from diverse matrices worldwide. Spectral Service AG developed the USP method for phospholipids in krill oil and established the AOCS method. The 31P-NMR method for phospholipid analysis is also endorsed by the ILPS as the official technique.
