Several basic rules that should be followed when maintaining the instrument

1. When the system fails, you can tentatively change certain states and change one parameter at a time. For example, to limit the problem of de-dimensionalization of chromatographic peaks, it is possible to change the mobile phase, change the protection column, change the analytical column, etc. in order. Doing some simple change steps may solve the problem.
2. Secondary comparison rules Before the hands-on inspection, the fault has been identified, or the solution to the fault has been determined. In other words, the solution has already been found. For example, during the injection process, the peak value of the internal standard was found to be low, and the repeatability could be repeated. If it happened to be low, it was a bubble in the quantitation tube. This rule can be used to examine the situation after the system has changed. Change flow backwards Two standards can be entered before the formal injection to check the stability of the retention time and the stability of the chromatographic peaks. If there are extra peaks in the gradient elution, you can elute it once with a gradient of no load (Is it really a problem?). Use this rule to avoid unnecessary changes and to determine the corrective action as soon as possible.
3. Replace the rules Replace the suspect parts with good parts is the best way to find faults. If you suspect that the detector caused noise, replace it with a good detector. If the fault is eliminated, there is a problem with the replaced detector. The size of the application of this rule is very large and small, from the replacement of the entire component to the replacement of printed circuit board integrated block.
4. Replacement rules This rule is used in conjunction with the substitution rules. After the good parts have replaced the suspect parts, the situation has not been improved and the original parts should be replaced. This minimizes maintenance costs and also prevents overstocking of parts. This rule applies only to a single failure. The principle of return does not apply to the following situations:
(1) The new component has been damaged (such as the pump gasket) when removed;
(2) Low price of parts (such as column lining filter);
(3) risk of damage if the original part is reinstalled;
(4) Parts that are regularly replaced.
5. Reference Condition Rules There are usually two reference conditions: 1 standard reference conditions; 2 test reference conditions.
Standard reference conditions, also called standard test conditions, are conditions that can be easily verified from one system to another and from one laboratory to another. The data measured with this condition helps to identify actual test and system problems. If the system pressure rises under certain test conditions, the pressure is normal under standard conditions. This shows that system abnormalities are caused by changes in the laboratory.

Mobile Type Halogen Operating Light

Halogen reflective Mobile Type Operating Light is widely used in various operation lighting occasions in hospital and clinics. 

Full close streamline lamp-body design of the  Halogen Shadowless Lamp  completely meets the demand of the sterilization and high standard of laminar flow purification in operation room.

Adopting more than 5280 slices of reflection mirror, guaranteeing 1200 mm lighting depth.

Lighting color of the  Halogen Surgery Light  is close to natural sunlight and helps the doctor to operate surger clearly and accurately.

The back-up bulb will start work within 0.2 seconds automatically in case the main battery is dead, ensuring the continuation of surgical operation. There's failure indication in the handle control panel to recommend the bulb to be changed after operation.

The detachable handle jacket can be used for high temperature (≤134℃) sterilized.

Digital-control circuit offers many functions:10 segment brightness selection, stepless lighting regulation, brightness memory, low voltage start-up and power on self test etc.

Life-span of OSRAM halogen bulb is up to 1500 hours. The bulbs can be changed easily.

High thermostability Germany ORSAM  lamp socket.

Balance arm can be optional Germany imported or domestic.
