MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-8-DB Supelguard Cartridge, 5 μm Particle Size

SUPELCOSIL™ LC-DB phases are specially deactivated for basic compounds. These columns provide less retention, better peak shape, and higher efficiency for organic bases than can be obtained on conventional reversed-phase columns.

Particle Size 5 μm
Type Guard Cartridge
Phase Reversed Phase
Length (Metric) 2 cm
Quantity 2/Pk.
For Use With (Application) HPLC
Product Line SUPELCOSIL Supelguard
200

MilliporeSigma™ Supelco™ Astec™ CHIROBIOTIC™ V Chiral HPLC Guard Column Cartridge, 5 μm Particle Size

Neutral molecules, amides, acids, esters and amines show considerable enantioselectivity on these vancomycin-based CSPs.

202

MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-18-DB Supelguard Cartridge Kit, 5 μm Particle Size

SUPELCOSIL™ LC-18-DB Supelguard™ Cartridges contain a SUPELCOSIL™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits.

203

MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-Diol Supelguard Cartridge Kit, 5 μm Particle Size

LC-Diol columns can be used to separate proteins by gel filtration chromatography.

204

MilliporeSigma™ Supelco™ Discovery™ RP-AmideC16 Supelguard™ Cartridge Kit, 5 μm Particle Size

Discovery™ RP-AmideC16 Supelguard™ Cartridges contain a Discovery™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits (2 μm porosity).

205

MilliporeSigma™ Supelco™ OPTI-GUARD™ C8 1 mm Guard Column

OPTI-GUARD™ sets the standard for low-impact, easy to use pre-column protection.

206

MilliporeSigma™ Supelco™ Ascentis™ C18 Supelguard™ Guard Cartridge, 3 μm Particle Size

Ascentis™ C18 is an extremely stable and reliable HPLC column that gives symmetric peak shape and excellent retention even for difficult compounds.

Pore Size 100 Å
Particle Size 3 μm
Type Fused-Core HPLC Guard Cartridge
Phase Reversed Phase
Length (Metric) 2 cm
Endcapped Yes
pH 2 to 8
Quantity 2/Pk.

MilliporeSigma™ Chromolith™ Phenyl Guard Cartridge

Added directly in front of the main column to protect it from chemical or mechanical contamination

209

MilliporeSigma™ Supelco™ Discovery™ HS F5 Supelguard™ Cartridge, 5 μm Particle Size

The Discovery™ HS F5 bonded phase provides reversed-phase separations that are distinctly different from C18 columns. However, compounds will generally elute within the same retention time window, making most C18 methods easily transferable.

Pore Size 120 Å
Particle Size 5 μm
Type Guard Cartridge
Phase Reversed Phase and HILIC
Length (Metric) 2 cm
Quantity 2/Pk.
For Use With (Application) HPLC
Product Line Discovery Supelguard
