DBDI-100 Dielectric Barrier Discharge Mass Spectrometer Ion Source Introduction
DBDI-100 is a mass spectrometer ion source that can ionize polar, weakly polar, and non-polar molecules in an open atmosphere at atmospheric pressure without sample preparation. The product can be used with the mass spectrometers of major mass spectrometer manufacturers to achieve direct injection analysis of gas, liquid and solid samples. It is suitable for food safety, drug analysis, environmental monitoring, clinical diagnosis, public safety and chemical research In-situ, real-time, fast detection.
Dielectric barrier discharge ionization technology is used to stimulate the inert gas such as helium in the insulating dielectric tube by AC high voltage to form a stable jet plasma beam, and then use the mechanism of penning ionization to realize sample ionization. Features
1.Fast analysis speed, more than 30 times faster than traditional mass spectrometry
2.No sample pretreatment, can be detected in situ, real time and directly
3.Wide range of applications, supporting in situ ionization of gas, liquid and solid samples
4.Low detection cost, no need for auxiliary reagents, green
5.Continuous, automatic, high-throughput injection
6. Lower detection limit (combined with LTQ mass spectrometry) is usually 0.5-50pg Technical Parameters
1) Carrier gas: Helium, above 4.7 (99.997%); Argon, above 4.8 (99.998%); Nitrogen, above 4.8 (99.998%);
2) Carrier gas speed: 0.2-5.0L / min, no carrier gas is consumed in standby state;
3) Ionization zone temperature: 25-250 ° C;
4) Mass range: usually 15-3000amu;
5) Lower detection limit: combined with LTQ mass spectrometry, solid samples are usually 0.5-50pg, liquid samples are usually 0.1-10ppb;
