HLB SPE Sorbent

Agilent Bond Elut HLB SPE

Hydrophilic-lipophilic balanced SPE sorbent for broad analyte retention, clean extracts, and reliable sample preparation.

Agilent Bond Elut

Agilent Bond Elut HLB SPE is a versatile hydrophilic-lipophilic balanced solid phase extraction sorbent designed for broad sample preparation workflows. Built on a monodisperse divinylbenzene and N-vinylpyrrolidone copolymer, Bond Elut HLB provides balanced retention across a wide range of compound polarities, helping laboratories achieve reliable cleanup, strong recovery, and reproducible extraction performance.

This sorbent is well suited for methods that must retain polar, moderately polar, and nonpolar analytes, including acidic, neutral, and basic compounds. Its broad applicability makes Bond Elut HLB a strong choice for laboratories handling multi-class extractions where sample complexity, matrix variability, and method robustness all matter.

General-Purpose HLB Extraction Chemistry

Bond Elut HLB is designed as a general-purpose SPE sorbent for laboratories that need one phase capable of supporting diverse analyte classes and sample types. The balanced hydrophilic and hydrophobic retention profile helps simplify method development while supporting dependable cleanup and analyte isolation.

High Capacity and Broad Method Flexibility

Compared with traditional silica-based reversed phase sorbents, Bond Elut HLB offers high adsorption capacity and broad chemical compatibility. Its polymeric design supports extraction methods across a pH range of 1 to 14 and works with common organic solvents, making it a practical option for demanding analytical workflows.

Designed for Complex Sample Matrices

Agilent positions Bond Elut HLB for use in environmental, biological, and food testing, as well as other applications where complex matrices can interfere with downstream analysis. Cleaner extracts can help reduce interferences, improve reproducibility, and better protect HPLC, LC/MS, and related analytical systems.

Supports Method Transfer and Routine SPE Workflows

Bond Elut HLB is designed to deliver performance comparable to other leading HLB sorbents, helping laboratories support method transfer with minimal disruption. This makes it a practical choice for both new method development and established SPE workflows that require consistency, efficiency, and dependable analyte recovery.

Chrom Tech supplies Agilent Bond Elut HLB SPE for laboratories seeking broad-retention SPE chemistry that balances versatility, recovery, and workflow reliability. For help selecting the right Bond Elut HLB format for your sample volume, matrix, or extraction method, contact the Chrom Tech team.

Key Definitions ▸
Hydrophilic-Lipophilic Balanced (HLB)
An SPE sorbent design that combines hydrophilic and hydrophobic retention characteristics so a wide range of analytes can be retained in a single extraction workflow.
Solid Phase Extraction (SPE)
A sample preparation technique that uses a sorbent bed to isolate analytes, remove interferences, or concentrate compounds before chromatographic analysis.
Polymeric SPE Sorbent
An SPE sorbent made from polymer chemistry rather than silica, often selected for broader pH stability, higher capacity, and versatile retention behavior.
Divinylbenzene and N-vinylpyrrolidone Copolymer
The polymer backbone used in Bond Elut HLB, designed to provide balanced retention for compounds ranging from polar to nonpolar.
General-Purpose SPE Sorbent
A sorbent intended to support a broad range of analyte types and sample matrices rather than only one narrow extraction mechanism or application.
Adsorption Capacity
The amount of analyte or matrix component a sorbent can retain before breakthrough occurs, which affects loading tolerance and extraction efficiency.
Matrix Interference
Unwanted sample components that can suppress analyte recovery, interfere with detection, or contaminate downstream chromatography systems.
96-Well Plate SPE
A high-throughput SPE format that allows many samples to be processed in parallel, often used in laboratory workflows that require greater sample throughput.
Method Transfer
The process of moving an established extraction method from one sorbent or platform to another while maintaining comparable retention, recovery, and reproducibility.
Frequently Asked Questions ▸
What is Agilent Bond Elut HLB SPE used for?
Agilent Bond Elut HLB SPE is used for general-purpose sample cleanup, analyte isolation, and concentration before chromatographic analysis. It is designed to handle a broad range of compounds and can help improve extract cleanliness before HPLC, LC/MS, and related workflows.
What does HLB mean in Bond Elut HLB?
HLB stands for hydrophilic-lipophilic balanced. This means the sorbent is designed to retain compounds across a wide polarity range, making it useful for methods that need broad analyte coverage rather than narrow selectivity.
What types of analytes can Bond Elut HLB retain?
Bond Elut HLB is designed to provide retention for polar, intermediate-polar, and nonpolar compounds, including acidic, neutral, and basic analytes. This broad retention profile is one reason it is often used as a general-purpose SPE sorbent.
Is Agilent Bond Elut HLB a silica or polymeric sorbent?
Bond Elut HLB is a polymeric SPE sorbent. Its divinylbenzene and N-vinylpyrrolidone copolymer construction helps provide balanced retention behavior and broad pH compatibility compared with traditional silica-based sorbents.
What sample types is Bond Elut HLB commonly used with?
Agilent positions Bond Elut HLB for use in environmental, biological, and food testing, and the product line is also presented as useful for complicated samples such as blood and urine. It is commonly chosen when sample matrices are variable or difficult.
Does Bond Elut HLB support high-throughput SPE workflows?
Yes. Bond Elut HLB is available in both cartridge and 96-well plate formats, allowing laboratories to choose between routine single-sample preparation and higher-throughput parallel processing workflows.
Why would a laboratory choose Bond Elut HLB over a more selective sorbent?
A laboratory may choose Bond Elut HLB when broad analyte coverage, method flexibility, and general-purpose extraction performance are more important than highly targeted selectivity. It is often a practical option for multi-class methods and early method development.
Does Chrom Tech help with Bond Elut HLB SPE selection?
Yes. Chrom Tech can help laboratories choose the right Bond Elut HLB SPE format based on sample volume, throughput needs, analyte profile, and overall sample preparation workflow requirements.
