simply to understand , the 连续光源 is one spare part of this machine, before we use one wavelength beam, now we have a scan; this spare part was first used in physics, optics, 天文望远镜, then later somebody used it into UV, then into ICP, now it is time to use it into AAS

for our AAS iCE3300, the acetylene 9psi and air 35 psi v.s 1 atm, so supposed the vacuum can be maximum 35psi or minimum 9psi for sample introduction.
如果将原吸雾化装置引入原子荧光系统,会出现怎样的结果, it will be no signal , because pressure too high and sample carrier run too fast.
