H2S gas of concentrations as small as 5 ppm could be readily measured.

Moreover, the shoulders around 20/23 ppm could be assigned to the methyl group in acetyl substituent in hemicellulose components.

The stronger peak appearing at about 6.9 ppm could be attributed to the proton of =C H.

By using standard samples which simulated the duckweed leaf, the Co concentration in the leaf in the order of 100 ppm could be quantitatively determined.

Residual chlorine dosages lower than 0.2 ppm could be effective in controlling fouling development if mechanical techniques of fouling control are also available.

For recent marine carbonates with low absolute REE abundances (<10 ppm total REE) the effect can be neglected, but for clinopyroxene, with significant REE abundances (Dy ca. 3 ppm, Yb ca. 2 ppm), it could be a potential problem (e.g. see [ 17]).

Lactulose hydrogen breath test by a standard technique [ 5] revealed two peaks; the first peak was at 110 min after 15 ml lactulose (24 ppm above basal, basal value 17 ppm); this could be related to SIBO.
