Sentence examples for ppm data from inspiring English sources

The difference in the total field intensity between the GDAS PPM and the absolute pillar is also measured regularly using a second PPM in order that the GDAS PPM data can be corrected to the absolute pillar.

The software also reads in the variometer and PPM data for the same date and time and outputs absolute observations in D, I, F, H and Z and associated collimation errors, plus the difference between the absolute and variometer values, known as spot baseline values.

The one-minute resolution magnetometer (PPM) data at Tirunelveli (8.7°N, 76.9°E, dip latitude 0.5°S) and Alibag (18.64°N, 72.87°E), operated by the Indian Institute of Geomagnetism (IIG), is used to study the electrojet strength on the days of observation.

The automatic data processing is carried out by a series of FORTRAN programs, which filter the one-second variometer and the 10-second PPM data to derive one-minute values, combine the one-minute and one-second values with daily baseline values (see later) and derive various data products and outputs useful for quality control of the data.

Unique, irregular minor peaks indicative of contaminants or impurities were present in all samples in the range from 0 to 4.8 ppm (data not shown).

The 1H HR-MAS NMR spectrum of intact M. bovis BCG control cells in D2O showed the presence of a well-isolated but excessively broad signal, presumably resulting from the low diffusion rate of mycolates within the cell wall, centred at −0.33 ppm (data not shown).

Spectral windows of 13 ppm (1024 data points) in the H dimension and 22.5 ppm (104 data points) in the N dimension were used, and the relaxation delay was 1.5 s.

The TPC was calculated using a calibration curve (gallic acid, 10 100 ppm) and data was expressed as GAE of dry plant matter.

The basis for this assignment is as follows: taking as a starting point the protonated olefinic 13C resonance at 127.2 ppm, HMQC data (Fig, 9a) indicate that this resonance corresponds to both of the 1H resonances at 5.47 and 5.50 ppm.

Total spectral area was then normalised to unity and spectra were binned at 0.005 ppm (4 data points).

At benzene concentrations < 0.1 ppm, the data primarily reflect background sources of the metabolites.
