The
packaging bags of milk powder need to be targeted at the nature of milk powder,
with the following functions: long shelf life, fragrance preservation,
oxidation and metamorphism prevention, moisture absorption and agglomeration
prevention. Therefore the material we will be used for this feature is BOPP/VMPET/PE.
1. The composite material of BOPP meets the
requirements of the milk powder, good printing and strength
2. VMPET has good light resistance, good light
resistance and good ductility. It has metallic luster.
3. PE has good anti-pollution sealing and low
temperature heat sealing.

Using FID detector, 6201 coated with sorbitol chromatography packed column, you can perform quantitative analysis on samples containing benzene and nitrobenzene in wastewater. If the detector of the instrument is changed to ECD (electron capture), the detection limit will be lower and the concentration will be lower. The method of extraction and enrichment can also be used to detect lower limit analysis. When the sample concentration is high, the TCD detector is used, so that a chromatographic column is used, the sample processing is simple, and it can be analyzed and determined to contain benzene, toluene, xylene or nitrate. The components of the mixed sample of benzene.
