In the product solution of the experiment with deuterated glucose e.g. deuterated phenol has the same retention time like phenol, but a different MSspektrum. Here the MS-spectrum of a compound is first compared with the literature data and than with the MS-spectrum of the deuterated compound. An increase of the molecular weight of a key fragment give the information, how many deuterium atoms are in this key fragment. Not for all compounds a clear quantification of the key compounds is possilbe, but for 3-methyl-2-butanon (1), hydroxyaceton (2), toluene (3), three different cyclopentanones (4-6) and three different phenols (7-9).

9 Fig. 3: Area % of identified products in the total ion chromatogram (Glucose conversion, most important deuterated compounds in black). Figure 3 shows the strong dominance of phenol in the total ion chromatogram. In addition, 3- methylbutanone, cyclopentanone and toluene show strong peaks. The methylcyclopentanones and hydroxyacetone are minor compounds. Trichloroethylene and the nitrocompound (Nr. 5 and 7 in Fig. 3) are artefacts from sample preparation.

10 Compound 1: 3-methyl-2-butanon Fig. 4: Non-deuterated product MS spectrum in comparison with literature: Fig. 5: Deuterated compound:

11 Compound 2: Hydroxyacetone Fig. 6: Non-deuterated product MS spectrum in comparison with literature: Fig. 7: Deuterated compound: In the deuterated sample the mass increase was m = 3 u. The main peaks are the same but a shift of the peaks m/z 32 and m/z 43 to m/z 44 and m/z 45 is obvious. The splitted CH2OH fragment is not able to have a OD- group therefore the increase of m/z31 to m/z 32 should be a consequence of the a CHD-OH-fragment formed.

12 This together with the mass increase of m/z 43 to m/z 44 and m/z 45 hints to a deuteration ration of 3 from 6 possible positions. Compound 3: Toluene Fig. 8: Non-deuterated product MS spectrum in comparison with literature: Fig. 9: Deuterated toluene: In the spectrum of the deuterated glucose experiment, there is a significant increase of mass of m = 5 u for m/z 93 to m/z 99 found. The five D-atoms are uniformly distributed at all C- atoms of the toluene. Four of them 4, but at lower intensity are found in the C5H5

13 -fragment at m/z 67, 68, 69 and 70 also. The last D-atom is separated by the formation of the C2H2-fragmente from the C7H7-Fragment. Compound 4: Cyclopentanone Fig. 10: Non-deuterated product MS spectrum in comparison with literature: Fig. 10: Deuterated product:

14 In the samples of deuterated glucose conversion, the molecular mass is increased by m = 4, corresponding to C5D4H3O. Now the fragments are investigated for an mass increase. At three C-atoms, not bonded to oxygen, the mass of the fragment is increased. There is one C-atom left, which has to be bonded to deuterium. The mass increase of m/z 55 and m/z 56 of m = 3 u to m/z 57, 58, 59, relative to the non-deuterated glucose experiments hints to 3 deuterium in the main fragment. This is formed by splitting of a C2H4D1 fragment. Only this way the strong peak at m/z 58 can be explained. The peak at m/z 30 prove the splitting off a C2D3 fragment with m/z 58, forming a carbonyl group. The three deuterium atoms can be found here again. Also the mass difference in respect of the molecule ion C5D4H3O, hints to this assumption
