i need to know what is the exactly instrument is needed to prepare quality control laboratory  in general ??

Well the term quality control can be applied to any lab environment, its what you do to make sure that the experiment or equipment is running smoothly.  For an experiment or industrial process, its something that you do that you already know the answer for, so you can tell if your setup is running correctly.

The range 50 to 80 degrees is above room temperature, so you need an electric heater and a power supply.  For small lab samples, a surface mount resistor is a good choice.  If precise control is needed, mount a thermocouple as close to the sample as possible and run the output to an A/D converter linked to a computer.  A very simple computer, or micro controller will do.  I used the original Apple for the job 20 years ago.  The computer should switch the heater on at a frequency proportional to the difference between the target and actual temperature.  This will give a damped settling to the target temperature and stability to better than 0.5 C.  For better stability, include the temperature derivative in your model.

A microphone and a recording device is all that is required for a "recording studio".  \n\nIf you want to be able to track, mix, edit, and master your own multi-track recordings you will need much more.  The core requirements to do this are:\n\nMicrophone\nPre-amp\nConsole/Mixer\nMulti-track Recorder (Tape, Computer, DAT, Etc.)\nOutboard Effects/Plug-ins (Compression, Reverb, Delay, Etc.)\nSpeakers\n\nThat setup should allow you to produce semi-professional quality recordings (depending on the quality/brand of gear and your personal experience).  If you use a Computer as your multi-track recorder you will also need DAW software and a multi-track interface.

a glass vial?    like a test-tube?    or a vacutainer tube (those things they use to draw blood into)?\n\nhow many do you need?\n\nhow soon do you need them?\n\nI could maybe 'hook you up'....

make sure you know the material you are being tested on

Use three test tubes, put equal amout of enzymes in all and put the substance they digest in both (equal amounts of course).\n\ntake a test tube(A) and put 2cm3 of Hydrochloric acid.\nTake test tube (B) and put 2cm3 of Pure water(pH7).\nTake test tube (C) and put 2cm3 of Sodium Hydroxide.\n\nshake them all a little just as you start the test.\n\nLeave them for half an hour at their optimum temperature and other factors.Make sure all factors among them are equal.\n\nAfter that, Test for the substance you put in (e.g test for starch using iodine if you put starch in).\n\nThe one with the most negative result is the optimum pH.

There are various methods. the method to be used is selected as per the conditions. Following are the most common of them.\n\n1) Use of head type flow meters like orifice or venturi\n2) Use of annubar, pitot tube\n3) Use of ultrasonic/ UV transmitter reciever or doppler frequency shift system\n\nFor details, following books can be referred\n1) Instrument Engineer's handbook- Bela G Liptak\n2) Measurement Systems- E. O. Doeblin

The meter should have some literature with it.\n\nWrite to the manufacturer and ask for it.

Look for caliper (spelling counts).  Specifically, Vernier Caliper, and micrometer.  \n\nThose are the two major precision measuring tools.  Try the starrett.com web site.  They have a sterling reputation for quality.

You're right, spectroscopy is the proper method...Below you'll find a link to a quick and simple explanation.

Laboratory certification of what?

I think the phrase you really want is "Total Quality Management" not leadership.  You may also want to look at "Sigma 6" and "Just in time inventory" as google searches if you're looking for that sort of information.

Note that both of the above posters are right but the fact that it's a very specialized test wasn't emphasized. If you are thinking of testing a sample of a steel alloy you have currently you will need to get a sample machined to the diameter and thread specified by the ASTM standard as the previous poster mentioned.

Actually the two are very different functions.\n\nQC is verifying that approved standards and procedures are being followed properly to produce a certain level of quality. Generally sampling or testing is employed to verify acceptable levels of quality.\n\nQA is oversight and assurance that a QC program is in effect and being properly administered.\n\nI am the QC Manager for my company. The company we provide construction and maintenance services for (our client) employs their own QA folks to oversee my department to make sure we are doing our job.

hi,\n\nmatlab sucks for this kind of thing.\n\nyou're better off getting an interface card from national instruments and using labview to do your data acquisition.\n\nhttp://www.ni.com/dataacquisition/
