| titleOfInvention | Multi-channel extraction device for pyrite sulfur in rock and soil samples |
| abstract | The utility model belongs to stable isotope composition mass spectrometer test field, concretely relates to a multichannel extraction device for pyrite sulfur in rock and soil samples, the device comprises a protective gas supply system, a sample reaction system and a product collection system, the protective gas supply system comprises a nitrogen steel cylinder gas, a nitrogen pressure reducing valve and a plurality of gas flow meters; the sample reaction system comprises a six-linked heating magnetic stirrer, flat-bottom triangular conical flasks, spherical condensation sampling devices and quark flow valves, wherein the number of the flat-bottom triangular conical flasks is the same as that of the gas flow meters, and the product collection system comprises two-stage absorption devices, the number of the two-stage absorption devices is the same as that of the gas flow meters. The utility model discloses a spherical condensation sampling device and flat end triangle erlenmeyer flask advance kind mode through quark flow valve and syringe, both guaranteed that the feeding does not expose in the atmosphere, can improve the device expansibility again, realize that the multichannel draws the pyrite sulphur in to a plurality of samples simultaneously. |
