COVID-19 blood plasma proton NMR spectra (raw)

1D proton NMR spectra from SARS-CoV-2–positive patients (n = 10) and healthy controls (n = 13), collected in a research study in Perth, Western Australia. Spectra are raw and require processing before statistical analysis (see ?covid for processed spectra).

Usage

Format

A numeric matrix/data frame with 23 rows and 29,782 columns:

rows: Spectra (samples)
columns: Chemical shift variables in parts per million (ppm)

Details

FIDs were acquired using a Carr–Purcell–Meiboom–Gill (CPMG) 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 at 4\(^{\circ}\)C.
