Cerex® and Narrow Bore Extraction (NBE) smart consumables

Solid phase extraction consumables

Tecan's suite of microparticulate solid phase extraction (SPE) consumables uses microparticulate sorbents with optimized small flow paths, to ensure greater contact with the analyte molecules. This enables better clean-up of the sample matrix, leading to cleaner sample extracts.

Tecan also offers a variety of sorbent chemistries, from state-of-the-art polymer technologies to unique target resins for more complex workflows.

Why microparticulate polymeric materials?

Capture efficiency refers to the ability of an SPE device to effectively retain or ‘trap’ desired analytes from the sample. SPE products that use large particle sorbents may exhibit significant analyte breakthrough during sample application, regardless of the chemical affinity of the sorbent for the analyte species. This is caused by the relatively large flow paths between the sorbent particles, which allow analytes to bypass contact with the sorbent and avoid retention (Figure 1).

In contrast, Cerex microparticulate sorbents have much smaller flow paths, ensuring contact with the analyte molecules passing through the sorbent bed.

Figure 1: 40-micron path


Figure 2: 10-micron path

Microparticulate polymeric materials allow for fast and efficient binding of analytes, resulting in smaller sorbent bed sizes

The difference between using 8 μm sorbent and conventional 40 μm sorbents of surface-matched chemistries was demonstrated by performing a loading experiment in an online cartridge format, measuring the breakthrough of a UV-absorbing analyte from each cartridge using a UV detector (Figure 3).

  1. Initially, the cartridge is bypassed; the detector signal reflects the level of analyte in the loading solvent.
  2. When the cartridge is placed into the sample stream, the absorbance initially drops and then recovers as analyte breakthrough occurs.
  3. The 8 µm cartridge captures roughly four times the analyte quantity compared to the 40 μm cartridge before breakthrough occurs, reaching total saturation immediately afterwards, as shown by the rapid recovery of the detector signal to initial conditions.
  4. In contrast, the 40 μm cartridge never reaches saturation, even after a significant period of time.

Most competitors

  • Large flow paths
  • Reduced sorbent contact
  • Analyte breakthrough possible

Figure 2: 10-micron path

Tecan SP

  • Much shorter flow paths
  • Increased sorbent contact
  • Improved loading
  • No breakthrough – robust, efficient and fast!

 

The Van Deemter equation applies to chromatographic separations

To obtain high resolution, increase the number of HETP (Height Equivalent to a Theoretical Plate) by decreasing the particle size of the sorbents as shown here.

Microparticulate polymeric material provides smaller elution volume

The high capture efficiency of microparticle sorbents allows much smaller bed sizes to be used in Cerex columns compared to conventional sorbents; a 20 mg Cerex column typically exhibits the same effective capacity as a 100 mg, 40 μm conventional SPE product.

The use of much smaller sorbent beds allows for the use of smaller analyte elution volumes too, as demonstrated in Figure 4.

Narrow Bore Extraction (NBE) technology offers higher performance than standard SPE

  Monodispersed particle size for maximum efficiency
  Less elution volume required
  Decoupled upper frit design retains maximum filtration capacity
  Air gap controls liquid flow for incubation workflows

NBE – next generation SPE

What is NBE good for?

  • Delivers fundamental redesign of SPE workflows with substantial improvements
  • Novel ‘Pocket Seal’ prevents sample flow until positive pressure is applied, allowing extended incubation steps on column and automation
  • Narrower particle size distribution improves extraction efficiency
  • Hot spot contamination eliminated
  • 5x smaller elution volumes allows injection into the MS instrument without concentration – just elute and shoot
  • Increased sensitivity and reproducibility allow use of less sensitive LC-MS equipment, reducing costs
  • Customers can reduce sample size, resulting in cost savings and simplification of the overall workflow

NBE and Controlled Flow Plate (CFP) condense SPE workflows

Resolvex_Smart_Consumables_10_720x480

 

Upper bed provides a barrier to liquid flow and filtration during pressure processing steps:

  • Upper chamber can be used as a reaction vessel
  • Liquid is retained until 15 psi of positive pressure is applied

 

  1. Air lock between the solid barriers prevents the flow of liquid from the upper chamber
  2. Monodisperse microparticulate bed with selected chemistry
  3. Proprietary ‘Inactive Chemistry Bed’ minimizes interaction of target analytes

NBE columns allow consolidation of workflow steps

NBE microparticulate columns deliver faster flow rates, lower elution volumes and reduced solvent consumption compared to classical SPE and supported liquid extraction (SLE).

  • New dual chamber design for high SPE performance
  • Microparticulate sorbent for high efficiency
  • Integration of pre-SPE steps in the reaction vessel
  • Filter for matrix clean-up
  • Air lock prevents dripping
  • Choice of sorbents for SPE or filtration

Positive Pressure Control with flow restrictors

Resolvex_PPC_Diag_Fig_A_720x480

Figure A.

Initial state. The manifold pressure builds to controller pressure that has been set. The effect of the restrictors is minimal in limiting flow from the manifold to the column reservoir.

Reservoirs start at atmospheric pressure.

 

Resolvex_PPC_Diag_Fig_B_720x480

Figure B.

Shortly after the initial state, the pressure builds in the column reservoir due to the fluid being held up by the flow characteristics of the column sorbent bed.

Restriction still has minimal effect.

Eventually the pressure builds enough to overcome the fluid flow resistance and fluid begins to pass through the sorbent bed.

Resolvex_PPC_Diag_Fig_C_720x480

Figure C.

Depending on the flow characteristics of the column’s sorbent bed, pressure in the column reservoir stabilizes.

 

Resolvex_PPC_Diag_Fig_D_720x480

Figure D.

The effect of the restrictor is maximized when fluid passes through one – or more – columns completely, and there is minimal pressure drop across the column bed.

The restrictor becomes the primary flow inhibitor of the gas as it passes through the column to the atmosphere.

Inhibiting the flow with the restrictors at this time is helpful in two ways: (1) the amount of gas used is minimized compared to a system with no inhibitors; (2) the pressure remains high in the columns containing liquid compared to empty or dry columns.

Applications

  • Analyte clean-up and enrichment
  • Life science research – protein desalting/digest clean-up, etc.

 

  • Food safety testing
  • Environmental monitoring
