Embodiment 1

[0075] (1) Take 2 samples of sandalwood red sandalwood wood, marked as No. 1 and No. 2 respectively, and take 2 samples of dyed red sandalwood wood, marked as No. 3 and No. 4 respectively. Among them, the samples must be heartwood parts, and there is no Pollutants, the measured masses of No. 1, No. 2, No. 3, and No. 4 are 1.15g, 1.07g, 1.12g, and 1.07g respectively, and the measured volumes of No. 1, No. 2, No. 3, and No. 4 are 1cm 3 、1cm 3 、1cm 3 、1cm 3 ;

[0076] (2) Put No. 1, No. 2, No. 3, and No. 4 into different headspace sampling vials. The specifications of the headspace sampling vials are: volume 20mL, round bottom diameter 20mm; Can be cut with a knife;

[0077] (3) Obtain the retention time-relative abundance total ion current chromatography and mass spectrum of samples No. 1, No. 2, No. 3 and No. 4 in sequence through headspace-gas chromatography-mass spectrometry (HS-GC / MS) Figure, wherein the headspace-gas chromatography-mass spectrometer parameters are set ...

Embodiment 2

[0102] The difference from Example 1 is: (1), get 1 piece of sandalwood red sandalwood wood sample, marked as No. 5, get 1 piece of dyed red sandalwood wood sample, marked as No. 6, wherein, the sample needs to be the heartwood position, and the sample surface No pollutants, the measured masses of No. 5 and No. 6 are 1.10g and 1.04g respectively, and the measured volumes of No. 5 and No. 6 are 1cm respectively 3 、1cm 3 ;

[0103] (2) Put No. 5 and No. 6 into different headspace sampling vials. The specifications of the headspace sampling vials are: volume 20mL, round bottom diameter 20mm; if the sample volume is too large, use a knife to cut it;

[0104] (3), obtain the retention time-relative abundance total ion current chromatogram and mass spectrum of sample No. 5 and No. 6 successively by headspace-gas chromatography-mass spectrometry (HS-GC / MS), wherein, top The parameters of the air-gas chromatography-mass spectrometer are set as follows:

[0105] A. The parameters of...

Embodiment 3

[0127] The difference from Example 1 is:

[0128] (1) Take one sample of sandalwood red sandalwood hand-stringed wooden beads, marked as No. 7, and one sample of dyed red sandalwood hand-stringed wooden beads, marked as No. 8. Among them, the sample must be the heartwood part, and there is no pollutant on the surface of the sample , the measured masses of No. 7 and No. 8 are 1.12g and 1.07g respectively, and the measured volumes of No. 7 and No. 8 are 1cm 3 、1cm 3 ;

[0129] (2) Put No. 7 and No. 8 into different headspace sampling vials. The specifications of the headspace sampling vials are: volume 20mL, round bottom diameter 20mm; if the sample volume is too large, use a knife to cut it;

[0130] (3), the retention time-relative abundance total ion current chromatogram and mass spectrogram of samples No. 7 and No. 8 were obtained in sequence through headspace-gas chromatography mass spectrometry (HS-GC / MS), wherein, headspace - The parameters of the gas chromatography-ma...

Abstract

The invention discloses a method for non-destructively identifying pterocarpus santalinus wood and pterocarpus dyestuff wood and products thereof, which comprises the following steps: (1) respectively sampling the pterocarpus santalinus wood and wood to be detected to obtain a sample 1 and a sample 2, and the volume and the mass of the sample 1 are equal to those of the sample 2; (2) sequentially putting the sample 1 and the sample 2 into different headspace sample injection bottles in a headspace-gas chromatograph-mass spectrometer; and (3) successively obtaining a total ion chromatogram and a mass spectrum of retention time-relative abundance of the sample 1 and the sample 2. And (4) observing the total ion flow chromatography, confirming a specific chromatographic peak, quantitatively analyzing the integral area of the specific chromatographic peak by using an FID (Flame Ionization Detector), calculating the integral area ratio of the specific chromatographic peak, and judging that the sample is the pterocarpus santalinus or the pterocarpus tinctorius. The method does not contain a wood sample solvent leachate treatment step, so that the detection efficiency is improved, the interference of a solvent is eliminated, and the identification probability is improved.

Description

technical field [0001] The invention relates to the technical field of wood species identification, in particular to a method for non-destructive identification of sandalwood red sandalwood and dyed red sandalwood wood and products thereof. Background technique [0002] Forestry is one of the important components of my country's national economy, and it is also the largest green economy in the world. With the sharp increase in the consumption of global forest resources, wood, especially endangered and precious wood species, has become the focus of attention of the international community. The genus Pterocarpus belongs to the leguminous family and includes about 35 tree species. It is famous all over the world for its elegant color, beautiful texture, hard and fine material, and high economic value. However, there are great differences in the economic and cultural value of different species of red sandalwood, especially sandalwood red sandalwood (Pterocarpus santalinus) and ...
