Abstract
Laser ablation devices and methods including laser ablation are provided. The ablation devices can include a deep UV laser. Dual-laser ablation devices are also provided. Biomolecules can be ablated using a combination of deep UV laser and nanoelectrospray, resulting in protonated sample molecules.
Claims15
An ablation device comprising:
- a deep UV laser;
- an electrospray ion source having an electrospray emitter;
- a focusing lens;
- and
- a sample target.
2 more elements
A dual-laser ablation device, comprising:
- a first laser and a second laser with adjustable firing time delay;
- a first focusing lens and a second focusing lens;
- and
- an electrospray ion source having an electrospray emitter.
1 more element
A method for laser ablation of biomolecules, comprising:
- applying a sample to a target;
- directing a beam of at least one deep UV laser at the sample;
- and
- directing an electrospray at the laser beam;
- and
- wherein the directing results in protonated sample molecules.
