Ghost peaks or cross-contamination can be caused by a ‘dirty’ needle. The SGE syringe cleaner ensures organic sample residues are vaporized out of the needle and is particularly useful for plunger-in-needle syringes. Operation is simple. Insert the needle through the septum into the heated zone, hold for about 30 seconds and then pump the plunger a few times to vaporize contaminants away. The device will accept needles up to 1mm OD and 100mm long. The cleaner has a very short warm-up period; it takes approximately 20 minutes to reach the operating temperature (250°C). The unit is thermostatically controlled for continuous use if required. A vacuum source of approximately 10 Torr from a water pump or mechanical pump should be connected to the unit. | |
