This holder can be used to couple any NewGuard directly to any LC column.
Sepax Technologies Inc Sepax HPLC Column HPLC GUARD Column, BioMix SEC-300, 3 µm, 4.6 x 50 mm
Utilizing proprietary surface technologies and 3 µm particle size, BioMix-300 phase is made of uniform, hydrophilic, and neutral nanometer thick films chemically bonded on the high purity and enhanced mechanical stability silica. The proprietary surface technologies allow the chemistry of thin film formation to be well controlled, which results in high column-to-column reproducibility. The nature of the chemical bonding and the uniformity of the thin film benefit BioMix-300 phase with high stability. BioMix-300 resin is produced from 3 µm spherical silica particles with a pore size of 300 Å. BioMix-300 columns are packed with a proprietary slurry technique to achieve uniform and stable packing bed density for maximum column efficiency. BioMix-300 phase is designed to ensure highest resolution and maximum recovery for a broad range of analytes such as bispecific mAb, hydrophobic samples etc.
Optimize Technologies OPTI-GUARD™ Biocompatible 1mm Guard Column, Amino (NH2), 5pk
OPTI-GUARD™ sets the standard for extremely low impact, easy to use pre-column protection. Designed for use with analytical (4.6, 3.0 mm i.d.) and narrow-bore (2.1, 1.0 mm i.d.) columns, the patented floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection every time. The best part? It's no larger than a standard fitting. Connecting the OPTI-GUARD™ requires no extra tubing, maintaining the minimal impact philosophy that has made the OPTI-GUARD™ line so popular. As always, custom packing is available. Key Features include: 5 disposable hand-tight holders and cartridges, a ZDV Connection, automatic adjusting to any manufacturer's column, no extra tubing is required for connection, the product does not effect chromatography, and it is no larger than a standard fitting.

YMC America, Inc C4-HG guard 200A 15um 50x30mm
YMC-Pack C4 is ideal for analyzing mixtures with a wide range of component polarity This is due to the C4 bonded phase exhibiting shorter analysis time while still maintaining high resolution when compared to longer-chain bonded chemistries YMC-Pack C4 (Butyl) columns are available with three pore sizes to accommodate optimum separations of virtually any molecular-weight compound The 120 phase is used extensively with non-polar peptides which are too strongly retained on C8 and C18 The 200 and 300 phase columns effectively resolve many classes of proteins and biopolymers
