Hollow cathode lamp technology exchange
Q1: When should I replace the element lights?
A1: When the detection energy suddenly drops, even disappears or the noise and drift suddenly increase, it can be used as the basis for replacing the element lamp.
Q2: What information should I provide for the purchase of element lights?
A2: Provide information such as the brand and model of the instrument using the element lamp and the element and serial number of the original element lamp for the salesperson to pair.
Q3: Why is the newly purchased element lamp different from the original lamp?
A3: Due to the different patents of different manufacturers designing and producing xenon lamps, it is often encountered that the replacement lamps are inconsistent with the original lamps; when purchasing lamps, it is necessary to indicate the brand and model of the instrument with the matching of the element lights on the contract.
Q4: What terms should be paid attention to in the procurement contract?
A4: In addition to indicating the matching instrument model, the warranty terms should be noted; most manufacturers' original xenon lamps are not covered by consumables, but Heraeus provides 5000 mAh hours of use and half-year shelf life warranty.
Q5: Why is the newly purchased element lamp black on the lamp body?
A5: Some elements that are very easily oxidized, such as K, Na, As, Se, etc., are easily oxidized and adhered to the lamp wall during production. But this does not affect the actual use, you can use it with confidence.
Q6: How should the element lights be installed?
A6: For instruments other than PE, the element lamp is inserted vertically into the base; the PE instrument inserts the lamp body into the mounting hole, and the code base is docked with the socket on the instrument; at the same time, the glass end of the element lamp needs to be noted. The window can't be touched directly by hand, so don't touch it when installing.
Q7: Why does the instrument display point not bright when the newly purchased element lamp?
A7: When the element lamp is working, the correct element must be selected in the software (multiple selection should be made when multiple elements are encountered) and the current value (should be 75%~100% of the maximum current printed on the element lamp package).
Q8: Why does the element light work differently when it is working?
A8: The elemental lamp has different filling gases depending on the element. The element lights glow orange and gray when they work.
Q9: Why is the energy of the newly purchased element lamp not enough?
A9: New element lights often need to be used for 16 hours to get the best stability and energy; if it does not affect the effect, please use 16 hours later to judge. At the same time, the height of the flame and the graphite furnace will also be affected; the set working current will have a great influence. We suggest that the operating current should be set at least 75% of the maximum operating current.
Q9: Why is the newly purchased element lamp not stable?
A9: Ibid. At the same time, the flame and graphite tube will also have an effect.
Q10: How to set the current during work?
A10: A current value lower than 75% of the maximum current is likely to cause lower light energy, resulting in a higher PMT voltage or gain value; when the energy is found to be low, the operating current should be gradually increased to ensure sufficient chemical sensitivity. .

PT141 Powder
Palatin Technologies Inc. (NYSE: PT-141) announced today that it has shown positive results in a Phase I clinical trial of pT-141 for the treatment of sexual dysfunction in normal premenopausal women.
The trial included 32 healthy female volunteers and evaluated their response to pT-141 and placebo in response to visual stimuli. Pt-141 was found to be safe and resulted in a significantly greater improvement in vaginal blood flow than placebo users (P< 0.05).
role
Such antibiotics first affect the outer membrane of sensitive bacteria. Drug ring part of polypeptide amino and lipopolysaccharide in the outer membrane 2 valence cations combining site to produce electrostatic interaction, destroy the integrity of the outer membrane damage, fatty acid part of drugs to penetrate the outer membrane, thus increase the permeability of cell size, lead to intracytoplasmic phosphate, nucleosides and other small molecules to escape, straight die cause cell dysfunction. Gram-positive bacteria do not respond to such antibiotics because they have a thick cell wall that prevents drugs from entering the bacteria.
