Most high explosives contain carbon, hydrogen, nitrogen and oxygen atomsA series of recent experimental results have overturned my long-standing thinking: “Using different isotopes and different modes to get the same results, it can be considered that elements have no mass spectrum interference.”Alt

Excellent corrosion resistance: PFA material can withstand various strong acids, strong alkalis, hydrofluoric acid and organic solventsInductively coupled plasma mass spectrometry (ICP-MS) is one of the most important spectroscopic techniques. It is a multi-element technique with extremely high sens

All flasks used in the reaction were heated under vacuum for 30 minutes and purged with N2 for 10 minutes.Part 1: 反应前的装置描述1.1: A 3 L three-necked round bottom flask equipped with mechanical stirrer (or magnetic stirrer), addition funnel and thermometer (or Dean-Stock; drying tube)1.2: All flasks use

They are typically used in analytical chemistry, biology, and other laboratory settings where the dispensing and capture of gases is necessary.PFA (perfluoroalkoxy) gas wash bottles are laboratory bottles that are designed to dispense and capture gases in various laboratory applications. They are ty

PFA/FEP separating funnels are made from a single piece of PFA/FEP material, which ensures there are no seams or joints that can leak or cause contamination.PFA/FEP separating funnels are laboratory tools used for separating immiscible liquids with different densities. PFA/FEP stands for fluorinated

PTFE reaction flasks are used for various types of reactionsPTFE (polytetrafluoroethylene) reaction flasks are commonly used in laboratory applications where chemical resistance and high-temperature resistance are required. PTFE is a thermoplastic polymer that is highly resistant to a wide range of
