Analytical instruments in clinical chemistry, uses and maintenance



Find the microplate you need by using our product selection tool and try a sample at no cost. Agilent cell metabolism assays detect discrete changes in cell bioenergetics in real time, providing a window into the critical functions that provide ATP. In general, a mass spectrometer bombards our sample with electrons and this results in the molecules fragmenting into charged ions. The ions are then ‘sorted’ or separated based on their mass-to-charge ratios. The different types of ions are then detected by what’s called an electron multiplier and the results are displayed as a spectrum.

This instrument can accommodate different sizes of plates which are scanned on top with UV, white light and/or fluorescent illumination. A centrifuge works on the principle of sedimentation, where the high speed of the rotation causes the denser particles to move away from the center while smaller, less dense particles are forced towards the center. Once the burner is connected to a gas source, the gas is forced by the gas pressure so that the gas reaches the top where the flame is ignited with a match or a lighter. To use a balance to determine the weight of a chemical, first put the empty container that the chemical will be in on the balance.

The atoms or molecules in the sample can then be determined by comparing them to masses that have previously been reported or by the molecule’s characteristic fragmentation pattern. A calorimeter is a device used to measure the heat change or heat capacity of chemical reactions or physical changes. The titration also known as titrimetry or volumetric analysis is a process used for accurately measuring volume. A spectrophotometer is a device capable of measuring light intensity as a function of its wavelength. It is used to obtain distilled water required for many lab tests as well as for the preparation of culture media.

Leasing equipment means you can get all that you need at a fraction of the cost compared to buying new, and in some cases, even buying used. Leases include the cost of repair and maintenance, so you don’t have to worry about the hassle of dealing with annual service contracts. When you opt to lease to cut down on your costs, you can choose to lease new or refurbished equipment. Depending on your location, the type of lab, and the equipment you need, you could spend anywhere from $50K to a few million. Fortunately, there are ways you can raise funds and keep costs low.

Changes to instruments, including software, become inevitable as manufacturers add new features and correct known defects. However, implementing all such changes may not always benefit users. Users should therefore adopt changes they deem useful or necessary and should also analytics instrument assess the effects of changes to determine what, if any, requalification is required. Testing frequency depends on the ruggedness of the instrument and the criticality of the tests performed. Testing may be unscheduled—for example, each time the instrument is used.

The spectrometer relies on an ion source, a detector system, and an analyzer to conduct a thorough analysis. The count includes both red blood cells and white blood cells , and can also include hemoglobin, platelet counts, and hematocrit levels. By analyzing a patient’s blood, their state of health can be more understood.

A watch glass is just a round piece of glass that is slightly concave/convex . They can be used for evaporation purposes and also can function as a lid for a beaker. They are generally held in a test tube rack specifically designed for the purpose.

List of Quality Control Equipment in Pharmaceuticals

The accuracy of diagnostic results heavily depends on the kind of equipment used to handle the analysis. As such, using standard medical laboratory equipment ensures consistent performance. Today’s medical and clinical labs are performing more and more sophisticated tasks. Not only has the amount of tests increased, the complexity has increased as well.

Scientists use classic analytical chemistry techniques and advanced equipment to separate, identify, and quantify matter. These electrochemical techniques provide powerful and versatile analytical options that feature high sensitivity, accuracy, and precision, utilizing relatively lower cost instrumentation than other methods of analysis. The Differential Scanning Calorimeter can be used to investigate the thermal properties of substances such as polymers and crystals. A small aluminum pan is filled with a sample and heated or cooled in a very precise furnace. The amount of heat absorbed or released by the sample, compared to an empty reference pan, is recorded.


Assembly and installation may be done by the manufacturer, vendor, specialized engineers, or qualified in-house personnel. Manufacturer-established installation tests and guides provide a valuable baseline reference for determining instrument acceptance. Any abnormal event observed during assembly and installation merits documenting.

Shop now for new and used products for materials research and testing applications. News-Medical.Net in no way endorses any of these products and services. Perform the PQ testing after installation of the change if similar testing is not already performed during OQ. An authoritative guide for validating stand-alone software, such as LIMS, is available.1 The validation process is administered by the software developer, who also specifies the development model appropriate for the software.

The machines are used to analyze blood samples to determine blood type, cross-match, or identify antibodies. While automated machines are helpful, proper training is necessary. Blood collection and analysis can detect a wide range of conditions including infection, cancers, anemia, diabetes, and more.

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. In a potentiometric pH meter, single or multiple glass electrodes, connected to a bulb selective to hydrogen ions, are attached to a metal rod. Different types of microscopes are developed to cater to the specific needs of the observation.

A laboratory thermometer is used for measuring the temperature of liquids. It can be made of glass or it can be a thermocouple made of different metals. A test tube is a glass tube with one end open and the other end closed. They are primarily used for qualitative assessment and comparison.

Once you have a reading, press the “tare” or “zero” button on the balance. Reweigh after adding the chemical to find the weight of only the chemical. Forceps are used to grab small things like solid chemicals that are broken into chunks, so they can be safely handled and added to containers. Tongs and forceps are for grabbing things that should not be touched by hand. Some tongs are specially made to hold beakers, others to hold test tubes, and so on.

Acryostatmaintains cryogenic temperatures for samples, slides, and devices stored within it by using liquid cryogens such as nitrogen and helium, however, there are cryogen-free models available that rely on electricity. It includes a microtome to slice the samples extremely thin while keeping an exact temperature. Such diseases or disorders can affect any of several components of blood, from blood cells, vessels, and proteins to bone marrow, so measuring blood cells and blood cell count can help diagnose and subsequently treat patients.

Also known as a conical flask, the Erlenmeyer flask was named after its inventor in 1861. This allows easy mixing and swirling of the flask without too much risk of spilling. The narrow opening also allows for the use of a rubber or glass stopper.
