Platisil® NH2 (New) - Dikma Technologies Inc.- A reliable partner for your lab.

Platisil NH₂ columns retain hydrogen-bonding compounds under three separation modes – RP, NP, and IC. Platisil NH₂ columns provide reproducible retention and selectivity with improved column lifetime.

Features of Platisil™ NH₂ Columns

·  Aminopropyl modified silica phase for multi-mode chromatography (RP, NP, &IC)
·  Improved phase ruggedness and stability
·  Excellent retention for polar compounds such as sugars, oligosaccharides, sugar alcohols, and other hydroxyl compounds, as well as DNA bases under RP conditions and vitamins A & D and hydrocarbons in the petroleum industry under NP conditions

EasyGuard™ Columns

• Universal design to match any brand column
• A variety of optional bonded phase material
• Does not affect the analytical column resolution
• Long lifetime column cartridges, high performance and low price

Balance

Guard columns provide protection against contamination with minimal impact on column efficiency. The column diameter determines both the sample loadability and column efficiency. A small diameter will decrease the column lifetime, but a large diameter will adversely affect column resolution. EasyGuard™ columns effectively profect the analytical column without adversely affecting the resolution or column lifetime.

Simple to Use

• Flexibility to move PEEK fittings
• Matches any brand analytical column
• Low dead volume connection
• Rugged 316 stainless steel column holder

Easy-Lok™ Coupler ^New!

When the EasyGuard™ guard column connects to a 250 mm analytical column, it can not fit in certain ovens (such as Agilent 1200) because the length is not long enough. The Easy-Lok™ coupler resolves this issue by removing the pre-tightened connecting pipe by wrench before using.
