Oasis HLB Plus Short Cartridge, 225 mg Sorbent per Cartridge, 60 µm, 50/pk

Use the Oasis HLB Plus Short Cartridge for sample cleanup and concentration to ensure maximum sensitivity. The lab equipment is made using the Oasis HLB sorbent, which is a universal polymeric reversed-phase sorbent specially designed to make the extraction of a wide range of acidic, basic, and neutral compounds from various matrices simpler and easier by using a simple, generic protocol.

The sorbent of the Oasis HLB Plus Short Cartridge is also water wettable. This enables it to maintain its capability for higher retention and excellent recoveries even if the sorbent runs dry. This ensures that you do not need to take any extra steps to prevent the sorbent beds from drying out during the critical steps before the sample is loaded. The 60 µm particle size variant of the Oasis HLB Plus Short Cartridge is well suited to working with viscous samples. The cartridge is versatile and can easily attach to pumps and syringes for reliable, positive-pressure flow to speed up the sample processing time. You can also fit removable reservoirs and use it on vacuum-assisted flow devices and certain automated systems.

Oasis HLB Plus Short Cartridge, 225 mg Sorbent per Cartridge, 60 µm, 50/pk FAQs

1. What type of samples is this cartridge best suited for?
The Oasis HLB Plus Short Cartridge is a versatile solid-phase extraction (SPE) cartridge that is well-suited for a wide range of sample types, including biological fluids (e.g., blood, plasma, urine), environmental samples (e.g., water, soil), and food samples. It is particularly effective for the extraction of a variety of analytes, such as:
Polar and non-polar compounds: The hydrophilic-lipophilic balance (HLB) sorbent allows for the retention of both polar and non-polar compounds, making it ideal for complex sample matrices.
Basic compounds: The sorbent has a strong affinity for basic compounds, enabling efficient extraction even at low pH.
Acidic compounds: While less efficient for acidic compounds compared to other sorbents, the HLB sorbent can still be used for the extraction of acidic compounds under specific conditions.

2. What is the sorbent capacity of this cartridge?
The sorbent capacity of the Oasis HLB Plus Short Cartridge, 225 mg, is 225 mg. This capacity indicates the amount of sorbent material present in the cartridge, which determines the maximum amount of analyte that can be retained. A higher sorbent capacity allows for the extraction of larger sample volumes or higher analyte concentrations.

3. What is the Oasis HLB sorbent?
Oasis HLB sorbent is a unique mixed-mode sorbent that combines both hydrophilic and lipophilic properties. This dual functionality allows for the simultaneous retention of both polar and non-polar compounds, making it a powerful tool for sample preparation.
The HLB sorbent is composed of a polymer matrix with both hydrophilic and lipophilic functional groups. The hydrophilic groups interact with polar analytes through hydrogen bonding and dipole-dipole interactions, while the lipophilic groups interact with non-polar analytes through van der Waals forces. This dual interaction mechanism enables the efficient retention of a wide range of analytes, regardless of their polarity.
