COVID-19 blood plasma proton NMR spectra (processed)

1D proton NMR spectra from SARS-CoV-2–positive patients (n = 10) and healthy controls (n = 13), collected in Perth, Western Australia. Spectra were pre-processed (residual water and signal-free regions excised, baseline corrected, and normalized to account for line-width differences).

Usage

data(covid)

Format

A numeric matrix/data frame with 23 rows (samples) and 27,819 columns (chemical shift variables in parts per million, ppm).

Source

Australian National Phenome Centre (ANPC), Murdoch University.

Details

FIDs were acquired with a standard 90\(^{\circ}\) RF pulse sequence on a 600 MHz Bruker Avance II spectrometer using IVDr methods for blood plasma (300 K, 32 scans). The spectrometer was equipped with a double-resonance broadband (BBI) probe and a refrigerated autosampler.
