5 Advanced Particle Platforms

All five of the Biozen particle platforms were individually designed and built by Phenomenex to take advantage of integral levels of performance, ruggedness, and reproducibility for protein characterization applications. Individually, each platform differs in the proprietary processing techniques used to control particle size and morphology.

  • Pore Controlled Technology

    The Biozen dSEC columns are packed with low pore volume silica coupled with a proprietary hydrophilic diol-type bonded surface chemistry that prevents the silica surface from interacting with protein samples.

  • Monosized Polymeric Non-Porous

    Meticulously controlled monosized particle technology secures incredible particle consistency that leads to improved and reliable efficiency. This innovative non-porous particle serves as the perfect backbone for complex ion-exchange chemistries.

  • Core-Shell Technology

    Using sol-gel processing techniques that incorporate nano structuring technology, a durable, homogeneous porous shell is grown on a solid silica core. This highly optimized process combined with industry leading column packing technology produces highly reproducible columns that generate extremely high efficiencies and sensitivity.

  • Thermally Modified Fully Porous

    Through a proprietary thermal processing series of steps, we eliminate micropores and further improve consistency, column efficiency, inertness, ruggedness, and reproducibility.

  • Solid Core Polymer Technology

    A highly engineered, non‑porous polymer particle featuring a dense, hydrophobic solid core that provides exceptional stability under native reversed‑phase conditions. Its inert, diffusion‑free architecture preserves intact, native biomolecular forms by minimizing secondary interactions while maintaining tight control over retention and elution.

FAQs

Yes, the guard columns for Biozen are biocompatible. Though the holder is not titanium, the analyte flow path is biocompatible.
dSEC-7 columns are shipped in 0.1 M Sodium Phosphate Buffer, pH 6.8 with 0.025 % Sodium Azide.
Chromatography is the separation of components in a mixture based on their chemical nature. Chromatography can be performed in either liquid (HPLC) or gas (GC) forms. Liquid chromatography, specifically High Pressure Liquid Chromatography (HPLC), involves a stationary phase (sorbent), a mobile phase (liquid) and the analyte or compounds of interest. Analytes or compounds of interest are injected onto an HPLC column (packed with sorbent that contains a variety of chemistries) in mobile phase. As the mobile phase, which is carrying the analyte or compounds of interest, travels across the stationary phase, the analyte or compounds of interest separate from each other as they interact with the stationary phase, each eluting from the column at various times. Gas chromatography (GC) is similar to HPLC in that is utilized with working analytes or compounds of interest that can be vaporized without decomposing. In GC, gas is used instead of a liquid (like in HPLC). As analytes or compounds of interest travel in the gas mobile phase and interact with the stationary phase, eluting at various times.
1 M is the maximum salt concentration that should be used when operating Biozen dSEC columns. Theoretically, a higher salt concentration should be compatible, however, as salt molarity increases, unwanted secondary impacts such as decreased protein solubility and increased column backpressure will arise.
The void volume corresponds to the amount of mobile phase in an LC system. In most separation modes the void volume would be equivalent to the amount of mobile phase needed to elute a compound that doesn't interact with the stationary phase and is hence unretained. In size exclusion, analytes are not separated based on chemical interactions with the stationary phase but rather their ability, based on size, to enter pores in the stationary phase. Therefore, in size exclusion the terms total permeation and total exclusion volume have greater significance than void volume. The total permeation volume corresponds to the amount of mobile phase in the system, including that in the pores of the stationary phase, whereas the total exclusion volume does not include the mobile phase within the pores of the stationary phase. Consequently, the total permeation volume corresponds to the amount of mobile phase needed to elute a compound that is small enough to completely enter into the stationary phase pores and the total exclusion volume is the amount of mobile phase needed to elute a compound that is entirely excluded from the stationary phase pores.
For short-term storage, it is suggested that mobile phase conditions continue to be run overnight at a low flow rate. For long-term storage, 0.1 M Sodium Phosphate Dibasic / 0.025 % Sodium Azide in water or 20 % Methanol in water can be used. When storing the column for extended periods it is important that buffer, salts, and sample first be removed from the column. Prior to storage, flush column with ~5 column volumes of 100 % water before switching between mobile phase and storage solvent.
The presence of microorganisms in the LC system is the most widely characterized source of unwanted chromatographic artifacts. Symptoms of microbial growth often first emerge through gradual increases in pressure that can signal impending compromised separations and eventual column failure. It is therefore important that the source be identified and addressed swiftly. Mobile phase bottles are often the most common source. It is generally suggested that the mobile phase bottle and solution be replaced entirely, particularly if the mobile phase looks cloudy or a film is apparent on the side of the bottle. Avoid the use of mobile phase sinkers where possible as these are a common source of contamination. If the pressure increase persists after replacing the mobile phase solutions, it is suggested that a system cleaning protocol be implemented (see ‘What are best-practice guidelines for system cleaning’ section).
Using high pH mobile phase, the retention of polar bases will be increased. Signal response does depend upon ionization state, so if we use high pH, we are actually de-ionizing our bases and should lose sensitivity. But this doesn’t happen actually. When we increase the retention of the polar base analytes using high pH, it elutes later in the gradient run and in a high percentage of organic (acetonitrile or methanol). For example, when using formic acid, the polar base analyte peak is eluting in about 5-10% acetonitrile, but when we switch to pH 10, the polar base analyte peak is coming off in about 30-40% acetonitrile. The increased % of acetonitrile in the source is what allows the ions to be ionized thoroughly, thereby giving you a better response in ESI-MS.
Proteins tend to diffuse very slowly due to their large size, which can make peaks appear broad, even on well optimized columns. By increasing the temperature, the diffusion coefficient of the solvents in the mobile phase are reduced, allowing for faster mass transfer of the protein analytes, resulting in better peak shapes. A further advantage of using high temperature is that selectivity can be manipulated by altering temperature, allowing for better separations in some cases.
We recommend 1 M as the maximum salt concentration that should be used in the mobile phase with Biozen SEC columns. Theoretically, a higher salt concentration should be acceptable and would not be incompatible with the columns. However, as salt molarity increases hydrophobic interactions increase, protein solubility decreases and column backpressure increases.
For comprehensive guidance pertaining to system readiness check, mobile phase preparation, column installation, condition/equilibration and recommended flow rate conditions, please review page 2 of the Biozen™ Care & Use Manual (GU54150623_W).
TFA is generally the preferred mobile phase buffer additive for reversed phase separation of peptides and protein. While some researchers prefer to use formic acid buffer where MS detection is used, the preference for TFA in the mobile phase relates to the fact that TFA is a weak ion-pairing buffer.
