Liquid chromatography (LC) is essential in many laboratories for the separation, identification, purification and quantification of various compounds in different matrices.
Components & Types of Liquid Chromatography Systems
“Classical” LC relied on gravity to get the mobile phase and sample through the column. But as smaller particles were used to improve separation power and higher pressures were needed to create the desired flow through the column, high-pressure liquid chromatography, or HPLC, was developed. Eventually, as advances in instrumentation continued and performance improved, the acronym HPLC came to stand for high-performance liquid chromatography. Systems that operate at pressures up to 35,000 psi are known as medium-pressure chromatography systems, and are typically used as part of a larger laboratory workflow to separate, prepare, or quantitate samples. Pumps vary in pressure capacity, but their performance is measured on their ability to yield a consistent and reproducible flow rate. Pressure may reach as high as 60 MPa (6000 lbf/in2), or about 600 atmospheres.
Modern HPLC systems have been improved to work at much higher pressures, and therefore are able to use much smaller particle sizes in the columns (<2 μm). These “Ultra High-Performance Liquid Chromatography” systems or UHPLCs can work at up to 120 MPa (17,405 lbf/in2), or about 1200 atmospheres. The term “UPLC” is a trademark of the Waters Corporation, but is sometimes used to refer to the more general technique of UHPLC. In addition to UHPLC, there is another subset of liquid chromatography called fast protein liquid chromatography (FPLC). FPLC is generally applied only to proteins, however, because of the wide choice of resins and buffers, it has broad applications. In contrast to HPLC, the buffer pressure used is relatively low, typically less than 5 bar, but the flow rate is relatively high, typically 1-5 ml/min. FPLC can be readily scaled from analysis of milligrams of mixtures in columns with a total volume of 5ml or less to industrial production of kilograms of purified protein in columns with volumes of many liters.
Not to be mistaken with FPLC, there are also flash chromatography systems on the market which minimize human involvement in the purification process. These systems are typically referred to as LPLC, low pressure liquid chromatography, and were designed to address the extremely time-consuming column chromatography stage which oftentimes bottlenecks the productivity of process labs. Lastly, there’s ion chromatography. Ion chromatography (IC) systems separate charged particles from a liquid and measure their concentration. IC systems can analyze particles such as anions, cations, organic salts, and proteins; IC is also very closely related to HPLC. They are typically used in environmental, manufacturing, food, pharmaceutical, and chemical industries.
With all of that being said, every HPLC instrument has the following key components:
- Sample injector
- Data handling computer
For applications that require close control of column temperature, column thermostats are usually included in the LC system. The other advantage of using a thermostat is that more reproducible chromatograms are usually obtained by maintaining column temperature. While organic-based chromatography usually involves column heating, the opposite is true for separating proteins.
There are many detectors for LC, some of which include:
- photodiode array (PDA)
- mass spectrometer (LC-MS machine)
- refractive index
- electrochemical, and
- evaporative light scattering (ELSD).
As for HPLC system prices, simple setups with a basic detector, injector, and pump are relatively affordable. This is especially the case if you opt for HPLC over UHPLC. However, if you increase the number of detection modules, add an autosampler, and upgrade to a high-pressure pump, the cost rises dramatically. By enrolling in our rental program instead of choosing to buy outright, your company can save a significant amount of time and money on a liquid chromatography machine.
A HPLC Machine Lease That Suits Your Needs
This off-balance sheet financing structure provides three options at the end of the term. The lessee has the option to return the equipment to the lessor, renew at a discounted rate, or purchase the instrument for the fair market value. Monthly payments are also 100% tax deductible which yields additional cash savings.
If you recently purchased equipment, Excedr can offer you cash for your instrument and convert your purchase into a long-term rental. This is called a sale leaseback. If you’ve paid for equipment within the last ninety days, we can help you recoup your investment and allow you to make low monthly payments. This also frees up cash in your budget rather than tying it down to the instrument.

Effect on Credit & Operating Capital
Leasing does not hinder your future borrowing ability and allows you to keep your business credit line open for expansions, staffing, and other operational expenses. Additionally, it strengthens the cash flow of your business and keeps cash reserves free for business development opportunities.
Unlike traditional financing and leasing companies, the Excedr program can accommodate refurbished/reconditioned equipment in addition to demo units. If you are looking for additional cost-savings, we recommend considering this option.
Speed of Approval
Excedr’s lease program allows you to respond quickly as your need for equipment and technology arises. You can be approved with minimal documentation and have the equipment you need in operation and generating revenue for your business quickly.
