Beautiful sunset there praxis!

Love all those Godsmacker, got a chuckle out of them.

Amanita muscaria sp.

And Great White Shark teeth. Both roughly 3-3.5 Million years old. Personal finds. The first upper jaw and the second lower jaw. Both from same formation.

nano-electrospray interface..femtomole sensitivity

 

[benzyme]

Just got this to control the hplc pump/run the gradients, and it can also control/record signals from the absorbance detector I have from a different manufacturer (ABI 785A). the software manual is 3028 pages.

the current setup is nearly identical to what I used to analyze IH's harmalas and Jork's p.brachy seedlings...and my own c.paspali experiments, in 2010.

 

[benzyme]

sensitivity is noticeably improved. I switched from orthogonal electrospray, with a sample tube of 100 um i.d., to capillary nanospray, 20 um i.d.

20 micron i.d. fused quartz silica capillary I flame-pulled to ~5 micron i.d., and cut with a ceramic blade. 100X mag., Zeiss KF 2

Holy crap! What would you use such a small tube for?

 

[benzyme]

low-flowrate/high sensitivity LC-MS.

I am reproducing what I remember from experiments I conducted 7 years ago in college, from my man cave.
I never actually prepared emitter tips, like I am doing now. they were purchased.
getting down to this level of sensitivity, analytes from intracellular serum may be characterized....from a single cell.


ideally, the tip would have more of a taper, and that is done with a laser.

Intracellular serum.. those are some choice words. !

Images from a spectroscope while teaching a basic spectroscopy lab. Two of the four lines of visible light that make up the Balmer Series of the Hydrogen atom.

Very nice benzyme for something so delicate :thumb_up:

Is this your first attempt at doing something like this?

 

[benzyme]

second attempt with 20 um. been practicing with 75 um.
yea, this is a recent practice, since I swapped out the ion source.
I have much greater control over the plume entering the ion transfer capillary,
and spectra like this is typical now.

 

[benzyme]

very easy to utilize capillary, because it's translucent, and can be troubleshot under a microscope.
I just switch out lines as needed.

Was lucky enough to catch this yesterday evening

danng, real nice..

My other love apart from psychedelics and entheogens.

Cracking german DMEs and hours of tuning and adjusting various tables/values for maximum power and efficiency.
