Two Series Of HPLC Columns From Hawach

Hawach is home to two series of HPLC columns-Xchroma series, whose columns has many types of stationary phases, with high quality; Echroma series which has fewer column types with lower price.
Advantages of HPLC columns
1.High column efficiency and large peak capacity;
2.Excellent batch stability;
3.Chromatographic packing inlet, high purity, and good uniformity;
4.A variety of columns with a variety of specifications. For instance, there are many different types and series of C18 columns, such as:
EChroma series C18, B type high purity fully porous spherical silica gel: purity > 99.99%; the same bonding technology as XChroma, which can be well-matched with liquid phase instruments of the low-pressure system. Competitive price advantage brings benefits to price-sensitive customers.
The Xchroma C18 series is available in four types, each with a different focus, as described in the following:
C18-Aqueous: Hydrophilic column to increase your buffer salt ratio in the 100% aqueous phase to maximize peak shape.
The advantages of these columns are less sample required, less required mobile phase, high sensitivity, and easy temperature control. However, their requirements for the flow cell of the detector, the piping outside the column, the joints, the injection valve, etc. are greatly improved.
Guard column:
Hawach also provides a guard column. HPLC columns are prone to clogging and damage, so some laboratories choose to use a guard column in front of the HPLC column to extend the life; the guard column typically includes: ferrule + column core + peek tube + peek connector.
