Thermo Nicolet IR200 Spectrometer

Thermo Nicolet IR200 Spectrometer investigation

Requires a custom power brick, multiple pins. Could not find power specifications. Power bricks do not seem to be available.

Laser was removed from this unit. This is a HeNe laser used “provies the reference signal for triggering data collections and measuring the stroke of the moving mirror.”

Dessicant spot indicates that the dessicant was exhausted. Dessicant appears to be a standard pack. Recharged dessicant in 250F oven for three hours. I’ll try to preserve the optics, I may be able to reuse them.

Requires ENCOMPASS or OMNIC software. I was able to find an OMNIC iso. Untested.

“The interferometer window in your spectrometer is made of KRS-5…” KRS-5 is thallium bromoiodide (TlBr-TlI). KRs-5 (TlBr-TlI) is a gorgeous red crystal commonly used for attenuated total reflection prisms for IR spectroscopy. It is also used as an infrared transmission window in gas and liquid sample cells used with FTIR spectrophotometers in place of Potassium Bromide (KBr) or Cesium Iodide (CsI) for analysis of aqueous samples that would attack KBr or CsI optics. It has a wide transmission range and is virtually insoluble in water. It is a useful alternative to AgCl since it is not photo-sensitive and for ATR applications it will transmit well beyond the 18 micron useful range of ZnSe.

The 2000 election and voting systems

After the 2000 ‘hanging chad’ election, the Election Commission report concluded that about 10% of votes are never counted or miss-counted. The Republican President and House didn’t much care, threw a few billion at the states some counties replaced the punch card machines w/ electronic voting machines. It made things worse. The election results are still untrustworthy, but in many places there’s no paper record to check but there is a poorly designed and poorly secured software program counting the votes. And yet worse, these voting machine companies are all private, and keep their software a secret, so there is no way to audit the software or check the election results. In the *rare* cases where security researchers have inspected the software and computerized voting machines, they have always proved easy to break into and subvert. Same with the centralized websites counting and recording the votes. Complete failure of democracy.

Elevian: daily injections of a protein called GDF11 can promote “the body’s ability to restore itself”

The company builds on research findings several years ago that if the bloodstreams of young and old mice are connected together, it seems to rejuvenate the older ones. … In a 2015 study, for example, scientists at Novartis found that GDF11 levels do not fall with age and that the protein actually inhibits rather than promotes muscle regeneration.

Republicans treat national security as a joke

Gosh, the earnest talk by Republicans on the paramount importance of scrupulous by-the-book handling of classified information was just a show for the TV cameras and gullible Republican votes.

“More than 130 political appointees working in the Executive Office of the President did not have permanent security clearances as of November 2017, including the president’s daughter, son-in-law and his top legal counsel, according to internal White House documents obtained by NBC News.” link

And for most of these folks, ‘does not have’ means the FBI checked them out and won’t approve clearance because they are a security risk. Some of these guys are known to have worked for hostile foreign powers.

Trump administration is allowing Russians to manipulate US elections

Intelligence chiefs to Senate: Nope, Trump doesn’t care about Russia by Heather Digby Parton, Salon

Sen. Jack Reed, D-R.I., asked a simple question that sent shockwaves through the hearing room. He asked the assembled intelligence leaders if the president had ever urged them to address the threat of further Russian interference.

He has not. When pressed, NSA Director Admiral Rogers said, “I can’t say I’ve been specifically directed to blunt or actually stop” future Russian attacks. CIA Director Mike Pompeo tried to defend Trump, but the best he could come up with was to say the CIA takes “all kinds of steps to disrupt what the Russians are trying to do.” FBI Director Wray said he had not been specifically tasked to combat Russian interference by the president. Coats said the same. When asked if the president has ordered an inter-agency strategy, he replied, “We essentially are relying on the investigations that are underway.”
