Clinical chemistry is the application of analytical techniques and instrumentation to the diagnosis and treatment of disease. The use of these techniques and instruments has increased the accuracy and speed of diagnosis, as well as the ability to detect and monitor disease progression. In this blog post, we will discuss some of the most common analytical instruments used in clinical chemistry. We will also discuss how each instrument is used to improve patient care.

Analytical Instruments in Clinical Chemistry

1. What are analytical instruments in clinical chemistry and what do they do?

Analytical instruments play an essential role in clinical chemistry, providing accurate and precise measurements of various analyses in biological samples. The most common type of analytical instrument is the spectrophotometer, which uses light to measure the absorbance of a sample. Absorbance is directly proportional to the concentration of the analyses, making spectrophotometry an accurate and precise method for quantifying analyses. Other common analytical instruments include chromatography systems, which are used to separate and identify analytes, and mass spectrometers, which are used to measure the mass-to-charge ratio of ions. These instruments play a vital role in clinical chemistry, providing critical information about the composition of biological samples.

2. Types of analytical instruments in clinical chemistry

There are many different types of analytical instruments used in clinical chemistry, each with its own unique capabilities and applications. The most common types of instruments used in clinical laboratories include:

1. Spectrophotometers
2. UV-visible spectrophotometers
3. Infrared spectrophotometers
4. Nuclear magnetic resonance spectroscopy (NMR)
5. X-ray fluorescence (XRF)
6. Inductively coupled plasma-mass spectrometry (ICP-MS)
7. Atomic absorption spectroscopy (AAS)
8. Ion chromatography (IC)
9. High-performance liquid chromatography (HPLC)
10. Gas chromatography (GC)
11. Capillary electrophoresis (CE)
12. Tandem mass spectrometry (MS/MS)
13. Surface-enhanced laser desorption/ionization time-of-flight (SELDI-TOF)
14. Isotope ratio mass spectrometry (IRMS)
15. Stable isotope dilution assay (SIDA)
16. Thermo Fisher Q Exactive GC-MS/MS system
17. Agilent 1290 Infinity II LC system
18. Waters Acquity UPLC H-Class System
19. PerkinElmer NexION 350 ICP-MS System

20. Shimadzu LCMS-8050 Triple Quadrupole LC/MS System

Each of these instruments has its own unique capabilities and applications.


Spectrophotometers are commonly used to measure the absorbance of light by a sample, while UV-visible spectrophotometers can be used to measure both absorbance and fluorescence.
Infrared spectroscopy is used to identify functional groups in molecules, while NMR spectroscopy can be used to determine the structure of complex molecules.
XRF is used to identify elements in a sample, while ICP-MS can be used to quantitatively analyze elemental concentrations.
AAS is commonly used to measure metal concentrations, while IC can be used to measure anions or cations.
HPLC is used to separate and quantify molecules, while GC can be used to quantitate volatile compounds. CE is used toseparate molecules by charge, while MS/MS can be used to identify and quantify specific molecules.
SELDI-TOF is used to identify proteins, while IRMS is used to measure the isotopic composition of a sample.
SIDA is used to quantitatively analyze stable isotopes, while the Thermo Fisher Q Exactive GC-MS/MS system is used for quantitative analysis of elemental concentrations.
The Agilent 1290 Infinity II LC system is used for HPLC, while the Waters Acquity UPLC H-Class System is used for UPLC.
The PerkinElmer NexION 350 ICP-MS System is used for ICP-MS, while the Shimadzu LCMS-8050 Triple Quadrupole LC/MS System is used for LC/MS.


Each of these instruments has its own unique capabilities and applications, and each can be used to perform a variety of analytical tasks in clinical chemistry.

3. How to choose the right analytical instrument for your needs

When it comes to choosing the right analytical instrument for your needs, there are a few things you need to keep in mind. First, you need to consider what type of analysis you will be doing. Will you be looking at small molecules, or large ones? What kind of detection limit do you need? How sensitive does the instrument need to be?

These are just a few of the questions you need to ask yourself before making a purchase. Once you have a good understanding of your needs, you can start shopping around for the right instrument. There are a number of different manufacturers out there, so take some time to compare products and prices.

Common sample abnormalities in clinical laboratory medicine include hemolysis, lipemia and jaundice, and of course veterinary clinics are no exception. The overindulgence of pets has led to an imbalance in food intake, resulting in an increase in the number of pets with hyperlipidemia. Also, many of the pets that require biochemical testing are emergency cases. They do not undergo a 12-hour food evacuation period. Others undergo biochemical testing after intravenous injection of fat milk. These are some of the conditions that lead to an increased likelihood of lipemia in pet samples. Here we will learn more about lipemia samples.
